Thanks a lot!
Thanks a lot!
I'm living in Greece and have not been able to use another sim card in my iPad 2 (purchased in the US with ATT sim card) and, in fact Apple told me to check into an international plan with ATT (this advice came from a support call supervisor!) which made me laugh as they had just told me it's an unlocked device. However, I see on this forum that some folks have to initialize the iPad and I have seen other discussions talking about changing the APN settings a topic about which I'm not conversant.
I will be going to the States for a bit and plan to talk to Apple about this frustration but any thoughts or ideas or recommendations are appreciated!
Try Cosmote, many locations for SIM cards:
COSMOTE: Mobile Internet on your computer
AT&T iPads should be unlocked.
Carriers in some countries sell locked iPads, but those are sold subsidized, so they're locked so that the carrier can recoup its subsidy by locking buyers into a data contract. If you paid full retail for your iPad, it shouldn't be locked.
There are no settings that must be changed to use an iPad purchased in one country in another country.
There are some things like International keyboards and local time zones you may want to adjust, but all you need is a SIM card with a data plan and you are all set.
OP, have you tried borrowing a SIM card that you know is working in another device? That might help you test.
OP, this might shed light:
iOS: Installing carrier settings updates
Note: If you insert a new SIM or micro-SIM card into your iPhone or iPad, you'll need to download the carrier settings for the new carrier wirelessly. Carrier settings are available only for iPhone support carriers and iPad partner carriers. If you're not using a partner carrier, you will need to set up the carrier's settings manually. Refer to your carrier for appropriate settings. iOS: About cellular data network settings (viewing or editing the APN)
APN username and password settings are not unique to the iPad or iPhone. If the carrier needs to set these, I would expect the technician in the cell phone store to understand this already - as he would have to set these for every device, not just an iPad.
Nothing specific to the iPad needs to be adjusted to use it with any data plan and GSM carrier.
We've set up hundreds of devices purchased is several different countries on both carrier partners and non-partners in over a dozen countries.
OP, see if you can nudge your carrier store people in this direction, to see whether APN is your prob:

This list might be outdated, but it might get them pointed in the right direction if they haven't tried.
And if they haven't already offered to swap out a SIM card that they know is working on another device, they've overlooked a quick way to check whether the SIM card or the hardware might be the prob. Often, SIM cards are just duds, even when new.
