XTZ SGP351 LTE APN for AT&T

[ScooterG]

Does anyone have a known working apn setting for the sgp351 on AT&T? The default isn't working and the apn I had in my Nexus 7 3G tablet is not working either...I'm using the same SIM in both.

Thanks for any help before I broach the subject with AT&T

No data works.

Also, the box states LTE Band 4

which apn settings do you have? which Bearer? leave it unspecified

[ScooterG]

I used exactly what you posted. Bearer is unspecified.

That's odd

mmsc: http://mmsc.mobile.att.net
mms proxy: proxy.mobile.att.net
MMS port: 80
MCC:310
MNC:410
APN type: default,supl,mms,hipri

Yes, tried that as well with the APN type filled in as well. I've also tried a couple of Cingular based APN settings. Off to AT&T!

Went to AT&T and they said the SIM just wouldn't work in a tablet period. I didn't mention it working in the Nexus. They couldn't figure out how to do a pre paid account in something that wasn't and iPad so I ended up at T-Mobile and a 3.5gb plan that gets 25MBPS down and 10 up.

That's quite interesting, but at least you got LTE and not just H+

I also have a SGP351 with an AT&T micro sim. I was wondering if there had been any changes in AT&T service capability for the tablet. I have a shared 10GB plan for my 3 phones so it'd be nice to keep it with AT&T.

I also tried all the variations of APN's posted here and elsewhere to no avail. I might have to hope AT&T starts carrying the Xperia Tablet, eh?
