TLDR - see last note Strangest thing - just switched from Sprint to VZW as Sprint's data is embarrassingly bad in my area. I ported 2 numbers - Mine to an iPhone 5, Wife to an iPhone 4S. Hers works fine. Whenever I go into an Extended area, any existing calls are dropped and I cannot place or receive calls or SMS TXTs. Placing a call results in a fast busy / reorder tone. Data works like a champ though - I can iMessage, browse, check mail, facetime audio call, etc... I've been working with VZW support via email and on the phone. We thought it had something to do with the SIM card so I swapped those twice, we've exchanged the phone in case it was internal antenna related, we've factory reset, wiped, restored, wiped again, etc.. VZW really has been good with their level 2 (or 3) support desk. We're going to try an iPhone 5S to see if that might resolve it and that is on order to arrive on the 20th of Oct, but I did some troubleshooting today - I had VZW swap my number to the 4S and Wife to the 5. Then we drove into an area I knew would be Extended. Both phones went Extended so we both attempted to place a call. Her # on my iPhone 5 went through no problem. My # on her iPhone 4S - reorder tone / fast busy. It would appear that the problem follows the number and is not related to the device, tower, SIM or anything else. I'm going to borrow a buddy's old 4G Android (ugh..) to see if I can reproduce the problem on a non Apple phone to confirm, but has anyone seen a case where a ported number won't roam? For ADD/TLDR - has anyone seen a case where a ported number won't make or receive calls when roaming?
