[Razer Phone 2 ROMs, Kernels, Recoveries, & Other D] ThatOneTimGuy:
Unfortunately for me and working at the moment, I don't have time to troubleshoot super in depth however since receiving the OTA update and implementing it yesterday, my mobile data has not reconnected (United States - Verizon). Earlier today when I saw you comment above that there was another OTA available (albeit for a different fix) I also installed that and rebooted as requested by the system after the installation was completed. Currently I still do not have mobile data and haven't received a call or text message without being connected to WiFi in I would say going on a little over a day.

Troubleshooting performed thus far when I have moments to spare here and there is as follows, not necessarily in the order performed:

(After pulling down the notification bar) Selecting Internet > Disabling WiFi and only leaving Verizon enabled

Leaving WiFi enabled but tapping on Verizon - this temporarily disconnects from WiFi and attempts to connect and utilize only the mobile data

Neither yielded differing results.

Selecting the " > See all " link (so the full Settings > Network & Internet page) - attempted both of the above toggling and let sit for varying amounts of time - does not reconnect to Verizon

Attempt to select the Fix connectivity option in the top right corner of the page - no difference in behavior both before and after a reboot

(On the same Internet page) Select the Gear icon next to Verizon - proceed to toggle options present on page one at a time, re-enabling singular options and trying pairings of the toggles available - no difference in behavior.

Attempt to turn off Use SIM entirely - after doing so, unable to turn back on until a device restart is performed at which point it is enabled by default.

Proceeding further down said page, under the System select option for changing the CDMA roaming mode - this is stuck on Automatic and cannot be changed to Home only.

Under Access Point Names, the initial page open displays two results:

1. Verizon * The selected option *

VZWINTERNET

2. XFINITY Mobile

VZWINTERNET

Selecting the XFINITY Mobile option and selecting the back arrow causes no change in behavior other than when re-entering the APN page it is now the selected option.

Selecting the Ellipses on the APN page and Reset to default while initially garner the three following results:

1. StraightTalk Verizon

TRACFONE.VZWENTP

2. Verizon * Selected option by default *

VZWINTERNET

3. XFINITY Mobile

COMCAST.RSLR.VZWENTP

Upon backing out of the APN page (no changes being made) and re-entering it, the APNS change to the two options seen above with the incorrect APN under the XFINITY option.

Resetting the APNs again and selecting the StraightTalk option (back out of the page and re-enter it) results in the same behavior as noted directly above - only two options are showing with the same APN - however now

neither of them are selected

.

Any other options after resetting the APNs causes the two results that show on re-entering the page to be selected correctly depending on option selected prior to backing out

but the APNs are both still set to VZWINTERNET

.

Returning the the initial Network & Internet page (directly beneath Settings) and selecting Network preferences

Each option turned on or off appears to make no difference

Switch to mobile data automatically was enabled on initial navigation to this page and all changed to these options DO stay updated upon backing out and re-entering.

All said and done, after the above troubleshooting and a few restarts peppered in between the various changes, nothing gets the Mobile service to return/stay enabled if it does happen to show it's checking against the Verizon network.

This includes:

Checked all System > Developer Tools options surround wireless connectivity or mobile network behavior - no changes to end results after either enabling or disable these.

Under System > Reset options > Erase downloaded SIMs (even though I did not have any downloaded) - no change in behavior and still disconnected.

Lastly, under Settings > About phone, the phone number is correctly populated however (under 'Device details') the SIM status will alternate between No Service (figA-NoService.png) and Emergency calls only (figB-EmergencyCallsOnly.png).

Any ideas why the initial March 31st release may have caused this to occur or recommendations on what to attempt next?

(I did a couple traces earlier as well using Developer tools and ensuring Network traffic was also being captured however I have not yet had the time to get them onto my personal machine and review them or use any additional ADB Debugging options)

Strikes me as more than a bit coincidental that this began occurring immediately after the OTA update from 3.7 (3.7 install was flashed onto the phone FRESH on March 18th.)
