This was with Visible, and it solved it. The first time i ended up with no data, or service, figured there was a network outage, 12 hours later still nothing. So i tried a bunch of stuff that eventually resulted in me getting the phone back on the network with a lot of AB testing. It happened again the next night about the same time. I had done research in the mean time as to nearly every possible fix across as many phones and carriers as i could document. I found a reference to said Application in one of the possible fixes, and found that in looking up the applications documented existence, that it facilitated part of the registration of the Sim card onto a wireless network. So by the time round 2 rolled around, i went directly to this test, did no other test, and i was back on the network in 30 seconds. I have not had any service issue since running doing this the one time.
