Hi all, just giving a quick 2 cents after my recent experience attempting to activate a Verizon S7 Edge on AT&T.
*Following a data reset you will need wifi for initial setup if you are using an AT&T sim card.
After following the guide in AT&T's web site for APN settings I was not able to get any data or mms service (this is using the NXTGENPHONE APN), so I did some experimenting. The following APN settings worked for HSPA+ data and mms, but NO LTE and NO MMS if connected to WIFI:
Name: ATT
APN: phone
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: http://ift.tt/OpjsVo
Multimedia message proxy: proxy.mobile.att.net
Multimedia message port: 80
MCC: 310
MNC: 410
Authentication type: not set
APN type: default,mms,supl,hipri
APN Protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
Bearer: unspecified
Mobile virtual network operator type: none
Mobile virtual network operator value: not set
So at this point I had NO LTE service and NO MMS IF connected to wifi. Utilizing the LTE Discovery app from the play store I could see that LTE was "not available" but on my wife's S7 she was getting LTE on Band 4. To make a long story short I got online to an AT&T chat rep who told me that HSPA+ and LTE are the exact same and they just show up different on different phones... THIS IS NOT CORRECT!
I educated the dumba$$ rep that HSPA+ and LTE are not the same, and asked to speak to a tech support SPECIALIST. After a short wait for transfer the final solution that worked was to have the specialist change the IMEI on file for my phone number to an AT&T branded Note 5 (I had an old one on the account and just used that). I then restarted the phone and had to wait about 10 minutes for the HSPA+ to change to 4GLTE signal. MMS now works when connected to wifi as well! Please note that this was achieved using the above mentioned APN settings- using AT&T's guide for NXTGENPHONE still results in NO data or MMS.
So the bottom line when transferring a Verizon S7 Edge to AT&T:
1. Use the above APN settings
2. Call AT&T and change your phone number's IMEI in their system to an LTE capable AT&T branded device (in my case note 5 worked)
3. Reboot and wait about 10 minutes for the signal to register
**DON'T let a representative tell you that HSPA+ and LTE are the same thing.. we're talking 8 Mbps vs 50+ Mbps download and 2 Mbps vs 20+ Mbps upload!
Cheers
