Didvyou get a fix?  What was it because my A12 has been doing the same thing.  The provider cant figure it out.  Samsung, same thing...go buy new phone what make you think it will be samsung.  I think that is the answer..

It is not so simple as I have followed all the troubleshooting steps, yet my phone does not IMS register.  When I turn on the phone my IMSI registers on 310-240 then I am shifted to 310-260 network.  This is by design but I get only an EDGE connection and IMS fails to register.  I can make phone calls, and get text messages, but no 4G/LTE connections.  I have done all the service providers troubleshooting steps and more, but to no avail.  I have changed service over three times, changing SIM cards and networks.  I even took the phone to samsung service where they scanned it and gave it a clean bill of health.  SIMPLE...it doesn't work, yet my Galaxy A11 will login with LTE service on every provider's service.  I have rewritten the firmware two or three times, reset the phone to factory, reset network settings until I am blue in the face.  SIMPLE...it doesn't work!

Please, don't mention clearing cache or APN settings.  I feel like I have done every APN posted one each provider.  I don't know how I got 4 years of trouble free service from Verizon unit my phone just stopped logging in to the service at all.  I took it to store and they said they changed something on the network, that is why it stopped working.  I checked the frequencies, GSM 1900 and b5 (800), so my phone does those frequencies!
