SIM card swapping
Luckily this is a curiousity question as the urgency worked itself out.
I have my Doubleshot connected to the Rogers network here in Canada, and I've tried other SIM cards before (i.e. T-Mobile) without issue. But this one had the representatives (and tier two support) stumped.
I walked into an Eastlink store (competing communications company although their roaming is done through Rogers frequencies) with a promotional flyer. We got talking about switching, and they offered to do a test to see if the phone is compatible. So I thought, hey, why not? So they popped an Eastlink SIM in my phone, turned it back on, picked up the network no problem. Well and good.
The problem occurs when she put my Rogers SIM back in. Boot the phone up and the network wasn't recognizing. No service. We went to Settings > Mobile Networks > Network Operators. The searching took forever then threw up and error. No networks to choose from.
The interesting part is that the Rogers APN's were present. I thought maybe the SIM card went bad. Luckily the Rogers store was across the street so we popped that into a feature phone, no issues. I then thought there was some weird (new) setting preventing it from connecting. So I booted into recovery and restored a backup from three days ago. No luck.
The problem ended up fixing itself, about an hour later, while waiting for the bus (after having given up). I made a few test calls to be sure. Since it's working now, it's merely a curiousity, but the issue stands: what would have caused this and is there any way to restore service faster? Using Tbaldens CM 10.1 if that helps.
Thanks for your thoughts.
