I don't really understand what scenarios this pops up in. I'm signing up with AT&T soon but off contract, I have my own phone. Then in a month or whenever the Lumia 900 hits I'll be popping my SIM out and popping it into a 900 most likely also bought at full price. Will I have this upgrade fee then just by moving SIMs even though AT&T has given me nothing contractually? People seem to refer to this as upgrades only as in something coming from AT&T?
Couple of things:
I started with AT&T back in like 1993. I switched to T-Mobile in 2007 and went back to AT&T in 2009. When i switched back to AT&T, I owned my own phone and went to an AT&T store to have my number transferred and get a new SIM card. The salesperson in the AT&T store, kept telling me I had to sign a 2 year contract. I kept telling him that I owned the phone and wanted a 30 day and out contract. He refused to do that. I left the store and called AT&T directly. Over the phone they transferred my number and sent me a new SIM card by mail on a 30 day contract. Total cost for the SIM card and postage was like $6.97.
When I got the new AT&T SIM card and activated it in my phone, there was an activation fee that showed on my bill.
The Lumia takes a micro SIM card, so if you need to change to a micro SIM card when you get your Lumia, there will probably another activation fee,
