Easy? No. What's the next step in the direction away from difficult? Trifling?
I walked in and had to leave my phone for repair. I said "I have this old Cingular (AT&T Mobility is a trademark owned by Cingular) phone I can use in the mean time, but it needs a full size SIM - do you have any adapters?" The sales associate said, no, I'll give you a new SIM. I had to wait about 2 minutes for him to change the account, put the SIM into the phone and call it to make sure everything worked. Two whole minutes. It took me longer than that to buy a case.
Oh, no charge. When the old phone came back it had a different SIM, and it took another two minutes for them to switch the account back and call the phone.
(Dealers [I used to be one] can get a handful of SIMs by asking for them - they're probably worth about a dime. I still have a few dozen lying around the house - they're not worth anything.)
