Make sure your phone is unlocked. Sprint phones that can work on the GSM network will also need to be unlocked. Ignore the "foreign SIM card" warning.

Thank you for posting. How does all this work with the Google Project Fi? I had a Steaight Talk plan with the old phone so when I activated the new phone with my old number through Straight Talk the phone works for calls and some text but I cant get data to work. Unfortunately I am not sure what the issue may be.

Please help!!! I've included a link below to a few Samsung phones we carry that will be fully compatible with Cricket and with also the best cameras.
Samsung is recommending an intenational version Note 5??? Any suggestions, based on experience, would be greatly appreciated.
I have been finding the specs of available iPhone 6s's confusing. Is there actually a technical reason for this? I currently have a Samsung S6. My Verizon galaxy s7 I use with a rogers simple card. It works mostly but due to the network differences caller ID and msg downloading will not work. I've set all the apn settings, talked with rogers and Verizon but no one can tell me how to fix this problem. Any suggestions? I am sorry but I am not too sure myself. It's possible that your S7 may just not be fully compatible with Rogers which is why you're experiencing these issues.
Am I allowed to switch carriers at any point if I'm not happy with them? Do I take my phone to the carrier and pay for a SIM card and go from there? Do I need to sign up for a plan? I don't understand any of this. I'm a novice. I'd like unlimited texts and calls. Thank you, Nikki. With the GU model, you can have it work with just about any carrier.
Usually a year or two. I've been using an unlocked HTC T-mobile G2 for the past couple of years, primarily to use its camera. I have been unable to figure out how to download apps. Each time I try, I reach a screen indicating that my Google Chrome browser is no longer supported and then instructing me to use the Google Play Store app to access Google Play. However, I'm unable to download the Google Play Store app. My phone is using Android version 2.
Is there any way for me to successfully update the operating system or to download apps? Thank you for any help you're able to provide. This was a really helpful article. I travel out of the country about once a year and would like to not have the T-mobile preloads. That's correct! You will need to double-check with T-Mobile prior to purchasing an un-locked phone.
But it is best to only purchase a phone that offers the current operating frequencies specified by your carrier. I have what seems to be a very pecular problem. Everything was working fine and I was able to switch the sim card from one phone to the other and it would still work fine. No sim card was ever associated with any of the phones IMEI numbers. Now suddenly as of this past Monday, I was no longer able to make or recieve calls on my T-Mobile phone.
I have been told that the phones I got off ebay have only been partially unlocked and that I am still needing to do a complete unlock to get the phones to work on the T-Mobile network again. I currently have the requests put in for unlocking these phones and will not know the results for another two days. Just wondering if you have ever heard of a phone being only partially unlocked, or am I being given the run around for an issue created by T-Mobile, and my only solotion would be to upgrade my phones to T-Mobile phones to continue my service with T-Mobile.
The issue you have described is not unusual. When cellular carriers change or update their systems sometimes 3rd party un-locked devices stop operating correctly.
Dave, I have the same issue. I was told that I have to purchase a T-Mobile phone to have service in my area. It took a month to get an answer from T-Mobile as to why my phone was not working anymore. I have a few questions:. Type your phone's name followed by "unlocked" into a search engine. Doing so will give you an idea of what most people have experienced in this area. You can also use your phone's model number e. I purchased an unlocked Samsung galaxy S6 phone and took it to Africa. This would really depend on the version of your Galaxy S6.
If it doesn't have the radio to support that particular network's LTE band, there is nothing to be done unfortunately. I have a Lenovo phab I'm trying to get to work on metro pcs. It worked once then stopped after I tried to use the dual SIM. Now it doesn't work.
