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.

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.

Generally, the process is fairly easy—ranging from filling out an online form to calling customer support—but each company handles unlocking differently. While each company may have slightly different requirements that you must meet before unlocking your phone, there are some basic things that they all require:.
