I have an ATT Samsung Galaxy S2 II unlocked SGH-I777. I am currently with Straight Talk service and have an ATT sims card. However, I can not send or receive any calls. Please advise me on what to do. Thanks.

In order to send them you need to look up the straight talk AT&T apn settings. A quick Google search will turn them all up.

No, you will need a Straight Talk SIM if you change to Straight Talk as your provider. You may use the AT&T network, but you will need a SIM from your new provider.

I received my S4 active already unlocked I then put my straighttalk SIM card in it it worked fine. So if cricket uses a gsm SIM card it should be fine. Just tell them you want an At&t compatible SIM card because you can browse internet and talk on phone at the same time.

I bought one from amazon and had to send it back because straight talk said that I could not use the phone. I would call straight talk.

The listing should be a leader to tell you. I use Straight talk. I hope that might help. Try checking in the listing. There were a ton of services that were listed where I purchased mine from. I love my phone, if it works with Cricket I'll guess you enjoy the phone as well. You will need to get a sims card if you do t already have one. They were. Cheap on Amazon.com. Randy

You'll have to first active your simcard then give AT&T; customer service a called to active your samsung mobile phone to the simcard. Hopefully I helped in time.

Most phones today that use a sim card are micro sim cards. If your phone is unlocked then try and use a att bring your own phone sim card. You will need to set the apn. Access Point name on the phone. Straight talk gives you the apn settings you have to apply them to the phone. Hope this helps you

Hey Jerry, so from my understanding you can switch your SIM card to the straight talk phone and you should be able to use it. I would definitely suggest asking them if you are able to use it with them just to double check though:)

I live in the US and had the same problem. I have AT&Tand; they told me it is because the phone is not assigned to a specific carrier. So there is no guarantee your data plan will work with an unlocked phone. They told me to call Samsung which got me no where. Samsung told me to call AT&T; and they were able to fix it.

My phone is a Samsung SGH A107 from a company called Pure Talk with the AT&T logo on the phone. It works just fine with my phone. Hope this is helpful.

I am not sure, since if Straight Talk GSM SIM card then it will work if not, then it will not work. Please verify with Straight talk on which frequency they are using for 2G voice and 3G Data, this phone has this:2G Network GSM 850 / 900 / 1800 / 1900 3G Network HSDPA 850 / 900 / 1900 / 2100 Thank you!NGP Team

I think it still requires a SIM card from AT&T. I am using my phone with StraightTalk and I had to put a SIM in it, but once the card was in it worked great! (Note: since this is an unlocked phone, you may have to enter the appropriate APNs (access point names) for your service.

You have to contact AT & T to see if it's unlocked. If it is you will have to find the accurate sim card for the Straight Talk plan. The sim card costs me approximately 90 dollars for the right one but once I found the correct one the plan is great. $45 a month unlimited and works GREAT. :) Good luck
