Using a phone from another carrier on Straight Talk Wireless


AT&T Cell Phone

This phone can be ported to Straight Talk.

If you haven’t already read my article on Straight Talk Wireless, you might not be aware that Straight Talk is one of the best deals in cellular.

There is some mystery around Straight Talk, and I hope to answer today one of the most frequently asked questions regarding Straight Talk:

Can I use my existing Verizon / AT&T / T-Mobile / Sprint / Tracphone / etc cellular phone?

The answer depends on the type of phone that you have.  Keep reading for more information

AT&T, T-Mobile or Any Unlocked GSM Phone

You can now take advantage of Straight Talk SIM, to use your existing phone on Straight Talk’s no-contract plans.  At this time, you must purchase the $45/month “Unlimited” plan to take advantage of this offer.  To take advantage of this, you simply order a SIM card from Straight Talk, place that SIM card into your phone and follow a few simple instructions.

Verizon Phones

Much like AT&T/T-Mobile, it is possible to take your Verizon Wireless device and use it with Straight Talk on the Verizon network through Straight Talk’s Bring your own CDMA Verizon Phone Program.

Anything Else

If you have anything besides an AT&T, T-Mobile or unlocked GSM handset, the answer is: Probably yes, but proceed at your own risk.  Before you try this, remember that you can buy Straight Talk Phones starting at FREE, and you can get a 10% discount on all phones if you buy them through Mr. Rebates, as described in our original post on Straight Talk Wireless.  Therefore before you try and do anything crazy, strongly consider selling your old phone and then buy a new phone that will work well with Straight Talk.

Sprint or Nextel Phones

If your phone is a  Sprint, Nextel, Virgin Mobile, Boost Mobile: Now that Straight Talk is using Sprint for their Android phone, the technical possibility exists to use one of these phones on the Straight Talk Sprint network.  However, this would be against Straight Talk’s terms of service, so it’s ultimately not permitted, even if it is now technically possible.

US Celluar or C Spire

You might be able to take these phones to Straight Talk if they are unlocked by first unlocking them and then using the Straight Talk Verizon Bring Your Own Phone program.  However this would be at your own risk; it likely would not be supported by Straight Talk.

Taking your Straight Talk Phone to another carrier

One interesting thing about Straight Talk phones is that you CAN use Straight Talk phones in certain situations on another carrier:
Straight Talk phones are designed to be used only with Straight Talk Service.  Under some circumstances, you may be eligible to have your Straight Talk phone reprogrammed to work with another carrier, but you must contact us to do so.  Not all Straight Talk phones are capable of being reprogrammed.

Get up and Running on Straight Talk

In closing, you can’t port a phone from any carrier to Straight Talk, but you can port from Straight Talk to another carrier.

However, since Straight Talk has a inexpensive phone selection starting at “Free” I suggest this:

  1. Sell your old phone on eBay, Craigslist or Amazon Marketplace
  2. Get started on Straight Talk with a new phone.  Be sure to get free shipping and get 10% cash back when you do this – don’t leave money on the table!

    I have an AT&T phone,A Rugby II. I have this phone because I am in the construction field and need a rugged phone. I allso have 270 phone numbers programed into this phone. I just switched to Straighttalk and nobody says I can still use the Rugby. I have got the unlock code from AT&T for the rugby,but I can’t unlock it. I would like to use this phone on the Straighttalk network,along with the 270 phone numbers I have in the phone. If I can’t find a way to do this,I probably will discontinue Staightalk. Any advice? Thanks,
    Tim Lipe

  2. luis says:

    Can you use a boost mobile phone on straight talk……the lg marqee

    • Wise Finish says:

      Luis, Thanks for your question.
      No, you cannot use a Boost Mobile phone on Straight Talk, as Straight Talk uses a different network than Boost Mobile. See the posting above for an explanation of what phones do and don’t work with Straight Talk SIM.

  3. Minh Scrudato says:

    Used Independence and AnySIM for the unlock. Wasn’t as straightforward as I thought it would be under 1.1.1 had to roll back to 1.0.2, apply a patch, upgrade to 1.1.1 and then used AnySIM. I thought it was a one click affair with the AnySIM app and 1.1.1. There is a newer beta that seemed to just come out that skips a few steps but there was a lot of disclaimers about it being very beta.

  4. Pam says:

    I am thinking about purchasing the Samsung Galaxy S (2) Skyrocket from ebay,its originally from AT&T. Would it be possible for me to use this phone on Straight talk? If so, will there be any disadvantage on the service and the phone itself?.

    your respond is greatly appreciated.
    thank you.

    • Wise Finish says:

      Hi Pam,
      Yes, the Samsung Galaxy S 2 (also called Samsung Galaxy S II) Skyrocket will work with Straight Talk, as it is an AT&T phone that operates on the 850/1900 Mhz bands.

      There won’t be any significant disadvantages on the service other than that you will be getting 3G service instead of 4G service with AT&T (though 4G service is not available in all markets yet). There will be no difference on the phone itself – it will operate exactly the same.

      Let us know how it works out for you!

      Thanks for your question.

  5. Jackie says:

    yes i was wondering if my samsung tranform will work with straight talk. its through sprint right now. but im thinking of switching to straight talk to save more money. my bill is way too high and prepaid is way cheaper.

    • Wise Finish says:

      Jackie, The Samsung Transform will not work with Straight Talk SIM. It is a CDMA phone. You would have to get another phone. Perhaps pick up a cheap used phone, or check out the Android or regular offerings from Straight Talk. See the other articles on this site for more information.

  6. Mike says:

    Is it possible to use a tmobile blackberry curve 8530 with straight talk? And if it is….what is involved in switching it over.


  7. Mike Stokes says:

    Is there a way to get a at&t lg encore gophone to work on straight talk. I know the talk and text is just a matter of putting the sim card in but the gophone apn settings are not able to be changed to my knowledge. Can this be setup to use the emai/web services on the phone?


    • Wise Finish says:

      I am unsure on that. You may want to contact Straight Talk customer service before you proceed. Or you can just give it a try and at most you’ll be out about $60. However, for that price you might just consider getting a phone you know will work with Straight Talk.

  8. mary says:

    can iuse lg a340 with straighttalk sim card dose it have to be unlocked

  9. mary says:

    i talked to st talk they said the lga340 had to be unlocked so what can i do thanks

  10. austin says:

    dose this work with a droidx or a iphone

  11. Kourtnee says:

    I have an htc sprint phone. Could I transfer my number from my current straight talk phone to the htc sprint phone, but continue buying plans from straight talk?

  12. AJ says:

    Hey i have a Samsung charge,is it possible for it to be used as a straighttalk phone? Will a straighttalk sim card work or can it be used?

  13. Kris says:

    I have a Devour smart phone that I bought from Verizon. Is this possible to transfer my straight talk plan to this phone?

  14. Sydnie says:

    Hi, I was wondering if a virgin mobile phone would work through straight talk. I have a LG Android phone. Could I just put a straight talk sim card in and use straight talk service?

  15. phil says:

    hey i have an unlocked htc pro2, will i be able to use a straight talk sim in it for service

  16. Chesery says:

    I really want to buy an LG Rumor from Virgin Mobile, can I use that phone with a straight talk plan?

  17. Vany says:

    can you use a virgin mobile on straight talk, i have a venture

  18. Whitney says:

    I have had service with straight talk for almost 2 years, not even a month ago I purchased an android phone, I busted the screen and didnt get insurance on the phone, I cannot afford a new phone at this time so I wanted to know if my straight talk SIM from my broken phone would work in an at&t phone that took a SIM card?

    • Wise Finish says:


      If it was a Straight Talk Android phone, it probably won’t work. If it was another Android phone that you purchased a Straight Talk SIM for, it probably will work.

      If the SIM doesn’t work, just spend the $15 and get a Straight Talk SIM, or get another Straight Talk phone (prices start at free).

  19. Alisa says:

    I have at&t service now. I have an iphone and an lg thrill and a sa7msung go phone on this plan. We have lousy service at home and so at&t sent me a mocrocell. we now have great service at home. Do you know if the microcell will work with my phones if i switch them to straight talk? And do you happen to know what at&t will have to say about the microcell when i cancel my current plan?

    • Wise Finish says:


      Unfortunately I do not know of any prepaid / no-contract carrier that supports Microcells. The only thing close to that would be t-mobile or republic wireless, both of which support Wi-Fi calling.

      I am not sure what AT&T will have you do with the microcell once your plan is canceled.

  20. Taylor says:

    can i use a blackberry curve from verizon with straight talk?

  21. Lynsi says:

    I have an At&T HTC Inspire 4g. I was wondering if I can use it on straight talk and what I need to do. Will data and pic messaging work if I can get straight talk on this phone? Thanks

    • Wise Finish says:

      The AT&T HTC Inspire 4G should work fine on Straight Talk SIM. Picture messaging may or may not work, if that is important to you contact Straight Talk Customer support before ordering.

  22. meesha says:

    I’m am very confused on weather you can switch a sprint/ verison . moblie phone to straight talk network ? so talk to me. I just bought a lg optimus elite phone and i would like to switch it over to straight talk, is this possible?

  23. Shannan says:

    can i use my pantech burst on straight talk?

  24. terry says:

    does this phoe has a sims card Samsung T528G GSM

    • Wise Finish says:

      This phone might work if it is unlocked. It might not work unless it is unlocked, depending on which carrier it was with originally. You might want to call Straight Talk customer support on this as it appears that this is a Straight Talk phone to begin with and they might just be able to send you a replacement SIM.

  25. Will says:

    Can I switch a Verizon phone that uses a SIM card to straight talk?

  26. Bryon says:

    I have a boost mobile, the phone I have is a samsung transform can I convert it to straight talk ?

  27. Rhandi Brady says:

    I am getting an Iphone 4 and was wanting to know if the micro sim is all I need to get started. Does the phone have to be reprogrammed, if so what does it cost to get it running? I am hoping to have a quick and easy activation. Do I need an ESN# or any other kind of number??

    • Wise Finish says:


      So long as your iPhone is locked to AT&T or T-Mobile OR unlocked, the following is true. All you need to do is to purchase the SIM, follow the given instructions and you should be operational. Sometimes people have issues with MMS, if you use that you may need to work with Straight Talk customer support to get it working. Be sure to use the links above and Mr. Rebates to save the most on your SIM & Service Card purchase!

  28. crystal says:

    Will my gs3 work with straightalk? Sprint? If not can I flash/unlock?

  29. Louise says:

    I have a samsung galaxy s 3,right now I have a contract with Verizon, when my contract runs out can I use my phone with straight talk?

    • Wise Finish says:

      Thanks for your question. No, you cannot use the CDMA Samsung Galaxy S III (3) on Straight Talk. Try Page Plus instead if you want to stay on the Verizon network, or just sell your S3 and pick up a GSM S3 or another phone that will work on Straight Talk.

  30. Lindsay says:

    I have a T-Mobile Samsung galaxy S II, will that work to switch to straight talk?

  31. will a dell streak 5 work on straight talk and if so what sim card should i buy

    the dell streak 5 is unlocked and i would like to keep 3g speeds

  32. Josh says:

    Hi, I have an HTC Incredible 2 ADR6350 on the Verizon Network. According to this article
    I can convert my phone. Is this correct? If not then do you have any suggestions for a comparable phone?
    Also what about bringing contacts over? Thanks

    • Wise Finish says:

      The procedure that Salon lists may work, but likely violates the Straight Talk terms of service. They do not allow “Bring your Own Phone” for Verizon CDMA phones, only GSM phones. They do sell a handful of phones that work on the Verizon network, including the Samsung Galaxy Proclaim, which is a nice little phone and it is the only legitimate way to get a Android Smartphone on the Verizon network through Straight Talk. To bring over your contacts – if you have an Android phone now, sync the contacts to your Google account (they may already be) and then when you sign into your new phone, the contacts will be there.

  33. liz says:

    I purchased an unlocked GSM Samsung Galaxy S2 T989 and want to use it with my Straight Talk $45 service plan. What all do i need to do to get it to work correctly?

    • Wise Finish says:

      All you need to do is use the links above to go to the Straight Talk site & their wizard will walk you through the process. If you have any more questions, stop back and ask!

  34. Cynthia Miller says:

    I need to know if i can use my old EVO phone from an old Sprint account. I have dropped and broke my LG phone with Straight Talk. Please reply back.

  35. Vanessa says:

  39. Sierra says:

    does the at&t motorola atrix hd work for straight talk?

  40. Becky says:

    I have a iPhone 4 through AT&T I am currently on the unlimited go phone phone plan which will not give me data was wondering if I could use the phone I have now on straight talk and if I will get my data?? Thanks in advance!!!

  41. Bryant says:

    I have the AT&T inspire G4, Will I still be able to use the hotspot and Wifi? or will I need to download an app for it to work agen and or need to root the phone?

    • Wise Finish says:

      I believe the hotspot will work, but I also believe it may be against Straight Talk’s terms of service. Check the fine print before signing up to avoid a surprise!

  42. jeremy griffin says:

    Hello, i was wanting to switch over to straight talk, however i was wanting to see if the htc titan II from att will work on straight talk without losing data spead or unable to send picture messages.

  43. chris says:

    Am I able to port my verizon phone number to a straight talk phone. My plan is up and I am paying month to month. I use my phone as a business phone and cannot lose the phone number.

    • Wise Finish says:

      Yes, you can port your Verizon number, but you won’t be able to take your Verizon phone to Straight Talk. If you get a new phone with Straight Talk, you can absolutely port the number. Keep paying Verizon until the number port request goes through, at which point your contract will be cancelled.

  44. Lisamarie says:

    Hi Wish,

    If I buy the note from AT&T or maybe Sprint can I use it with Straight Talk’s service? I read about the CDMA on other posts just still want to clarify this. It is really messed up that you have to buy another of the same phone just to use a cheaper phone service….

    Anyway, let me know.

    • Wise Finish says:

      Lisa, If you are going to buy an unlocked note – check the links above for the Galaxy Note, which will take you to, who has a great return policy and a great selection of phones. Also, check out if you’re willing to take more risk but save more.

      It seems odd that you need to purchase a more expensive phone to save money on your phone contract, but the TRUTH is that you are paying for that phone through high monthly rates on the contract carriers. So, pay a little bit more up front and a good deal less every month for 2 years – and you can save thousands!

  45. danielle says:

    I want to go to boost mobile, can i take my straighttalk phone number with me? If so what is the process, what will i need…I like straighttalk, but the reception in my area is very bad, no matter the phone.

    • Wise Finish says:

      Yes, I believe you can transport your Straight Talk number to any carrier. Keep your Straight Talk service current, then sign up for Boost and request a number port.

  46. jason76 says:

    Why cant a lg optimus showtime work in my area when i hear its a verizon type phone and im around verizon towers

  51. Jen says:

    I have a Samsung Galaxy S from Sprint and was wondering if i could switch it to straight talk? I also have an HTC Inspire from ATT and was wondering if that would work?

  52. Margaret says:

    What about Samsung GS3 from US Cellular?

    • Wise Finish says:

      US Cellular phones won’t work with any current ST program. Sell it and get a Verizon phone (port using CDMA Bring Your Own) or any unlocked GSM phone (port using Straight Talk SIM)

  53. emslav says:

    Wise Finish,
    I have a very old Straight Talk phone (Samsung) it does NOT have a sim card. I was given a newer AT&T Samsung phone which takes a SIM card…Can I switch to that without having to purchase the $45 plan a the $30 is all I need and have used since Straight Talk has been available? Your help would be appreciated. So glad I found your page.

    • Wise Finish says:

      You cannot switch to that phone without buying the $45 plan. The $30 plan only works with Straight Talk branded phones.

      What you CAN do though is run your new phone on another carrier that supports AT&T, like H20 Wireless or Red Pocket Mobile. They sell the AT&T SIM and offer a variety of plans to meet your needs at a lower cost. Straight Talk only allows the $45/month plan with their SIM Card. Check out to compare your options.

  54. Lisa says:

    I have had ST for about 5 years with a phone that doesn’t have a SIM, it is very old. I have been given a Samsung newer phone than mine it is an AT&T with AT&T Sim; can I transfer my ST phone number to this new (old) phone without having to purchase the $45 plan when the $30 is enough?

    • Wise Finish says:

      No. If you need a lower priced plan and want to stay on AT&T, check out H2O Wireless or Red Pocket Mobile.

      • emslav says:

        Thanks, but I live in the UP of MI and we only have the options of Verizon and At&t in cell service. I ended up having to purchase another ST Verizon phne for over $100 without sim card and it Sucks! No cell reception at all. I only have the $30 plan but not really worth it at all.

        • Wise Finish says:

          Yes, I know the cell service in the Upper Peninsula of Michigan is limited. I would suggest returning the ST phone if it is not working for you (they allow this).

          If Verizon will work for you, check out Page Plus. If AT&T will work for you, check out Red Pocket Mobile or H2O Wireless if you are looking to stay on a cheaper-than-the-unlimited plan for around $30. Check out for more options.

  63. Carrie says:

    I have a T-Mobile MyTouch 4G Slide that I want to convert to a straight talk plan. It was originally a contract phone and has not had service for some time. Can someone tell me if this is possible and point me in the direction to get it up and running. Thanks!

  64. Mike says:

    I currently have straight talk. I was wondering if I have a iphone 4 from Verizon, if I can use it on straight talk. Also my area offers both AT&T and Verizon coverage, I want to stick with the Verizon coverage because I get no signal with AT&T, is there anything that I should be looking at more carefully when buying a phone to use?

    • Wise Finish says:

      Mike, You cannot use a Verizon iPhone on Straight Talk at this time, as they are explicitly excluded. Verizon wants to keep the premium features – LTE & iPhones – for their big dollar contract plans.

      Check out Page Plus – they might be able to take your iPhone just fine – they also use the Verizon network. Check out Phone Bill Cut to compare your options and learn more about Page Plus.

      When buying phones in the future, if Verizon is all that works, then just keep getting Verizon phones and running them on a no-contract network.

      If AT&T or T-Mobile work in your area, then get an unlocked GSM phone, which will give you the most freedom in the US and abroad.

  65. Devan says:

    A store near me advertises that you can “bring your own phone” to Straight Talk and any CDMA phone will work. I have a Samsung Galaxy 2 on Virgin Mobile. I can’t find anywhere whether I can switch it to Straight Talk or not.

  66. mema says:

    I want know will you need to unlock the phones from other companies for the straight talk to work or can you just put the sim in the phone and have it work that way

  70. court says:

    im currently a verizon customer but want to switch to straight talk and have to break my contract. can i use my Android RAZR M?

  71. court says:

    I wrote on here the other day and I checked the two boxes to notify me of new comments and follow up comments on here and I keep receiving emails. How do I block it now that u answered my question?

  72. Devin says:

    My brother has a Sprint iPhone 4. It was previously activated with Sprint, but now it’s disconnected. How could he convert the service over to Straight Talk?

    • Wise Finish says:

      First, he would need to get the phone unlocked & jailbroken. Then he could place a GSM SIM card from Straight Talk into the phone. You may need to use something like the Gevey SIM as well to make it work.
