Activating unlocked Motorizr z3 on Sprint

Purchased a Motorizr z3 for the wife to use in UK on a recent trip. She bought a sim and minutes on the Lebara network there and it worked fine. She's now returned and I'd like to use it to replace her Motorola 730i on Sprint. If I simply replace the sim card in the Motorizr with the one from the 730i it cannot find the network. How do I activate the Motorizr on the Sprint network with the phone number from the 730i?

can't do it

In reply to: Activating unlocked Motorizr z3 on Sprint

You can't use a GSM phone (uses a SIM card) on Sprint which uses the CDMA network. The technologies are incompatible. You could on use it on At&t or T-mobile as long as the phone is unlocked.

The Motorizr does come up and connect with the AT&T network here in the US; AT&T coverage where I live really sucks, so that's why I wanted to switch it to Sprint. While the phone does connect with the network it won't make outgoing calls - I get a message about 'that feature isn't enabled' so I suppose I'll have to get an AT&T account and number.

If ATT service is poor at your location...

In reply to: thanks

...why not try out T-Mobile(?) They also would let you bring in that quad-band GSM phone for their service. Buying a pre-paid SIM wouldn't set you back much either if you wanted to first evaluate their service/reception in your home/etc.

It's something to try

I might do that, but I think T-Mobile service is nonexistent here. There are no equipment vendors here at all, and I know of nobody who has a T-Mobile phone here. I'll look into it, though.
