I recently visited Taiwan for a 3 weeks and purchased a prepaid SIM on their network to use while I was there. Everything worked great. However, when I came back home to the US and put my Verizon SIM back in the phone, I no longer have mobile data working. I can make and receive calls without issue, and WiFi and Bluetooth are no problem.
I have reset the network multiple times and that did not work. All of the updates have been installed. I have powered down and removed the SIM card and put it back in and powered back up and no luck. Verizon 3G is showing up in the top left corner of my iPhone 6.
What should I do to get the data connection working?
Thanks for any assistance you can provide.
