I think he's in time to take it back if all not working correctly. One will check tomorrow.
I have a Motorola Cliq XT with an early Android OS. I was told to bring it up to date would cost more than the phone was worth cos they needed it to be sent back to MR. With the American sim, it was a nightmare, but always, with the UK sim it works like a dream. (Touch wood.) I persevered with it because (gasp) it's a bloody good phone and while in England at least, hardly ever needs charging. (twice a week, compared to twice a day sometimes in Texas.) I have no idea what was running in the background with American T-mobile, but it was consistently bad for several years while being consistently good here in the UK.
In the early days I tried trotting up and down my road in Texas and it seemed to work as a GPS, but I was never sure if it was really GPSing or getting data off the masts. Can such an old phone really be a GPS receiver? Certainly, the Sony just a short while later had GPS and with an INERTIAL system for tunnels etc. Rather impressive filling in of the gaps.
