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

1st LTE must be enabled with your AT&T account, to do so, you need an LTE phone AT&T branded, so they can input the IMEI number in your account, thus enabling 4G LTE, there isn't a way around it

Still a no go but kudos for trying. The SIM came from a AT&T LTE Sierra Wireless Data stick. Not sure why it works in the Nexus 7 and not the Xperia. Guess I'll have to pay up for some pre paid service.

Thanks again!

The sim isn't from the tablet. Thanks again!

Yep. LTE 4 works fine on the data stick. HSPA+ works fine in the Nexus7.

Would 3G work?

3G and H+ should work
