Can AT&T 3G frequency modems/tablets use the PAYGO smartphone data packs addons?

[jonesfones]

I have an Unlocked Att Mifi and I want to know if any one is using it on the pre paid $25 data package that includes 500MB of data. I did heard that I have use the Dataconnect plan for the mifi to work but can a prepaid go phone sim work too?

Att prepaid broadband is pricey. $15 for 100 megs w/1 day expiry. $30 for 300 megs, one week.
$50 for 1 gig, 30 days. Att add on data packs for paygo and smartphones is $5/10 megs, $15/100 megs, $25/500 megs , all with 30 day cycles. Big difference in data prices and expirations dates. Is it possible to use an Att compatible non phone device like a tablet or usb broadband modem to tap into the add on plans ?
Does Att block non phone devices (like how Tmobile blocks non phone devices on their hot new $30 /5 gig 4g plan?).

Can one use unlocked but not Att branded Tablets and usb modems to use the add on packs?
If anyone has any experience with this , please post your results.

Thanks. (There are way more Att frequency type unlocked tablets and usb modems then Tmobile type out there.)

Assuming you set the APN right, why not? I can use my GoPhone SIM in my iPad and share the data packs.

Interesting and and a good starting point. I'd assume if something as hot as the ipad is allowed then lesser Android tablets would be as well as modems.

Frankly, the Tmobile new five gig plan conquers anything Att offers , BUT most of the unlocked modems and tablets appear to offer the Att 3g channel (850/1900mhz UMTS/HSPA, etc) not Tmobile (1700 mhz AWS).

Most international travellers to this country with unlocked modems are much more likely to have Att channels then Tmo ones too, I believe along with their (usually) native 2100 mhz 3g channel.

Plus Tmo blocks non phone imeis on their new plan. That would include modems and I assume tablets too. Especially Tmo branded ones. Tethering might be an option.

The Att gophone data packs are a much better deal then Att's prepaid broadband packs with longer expires, lower prices and rollover. PLUS you can always pop it into a phone and use it for its original purpose.

Idk if you can tether this but apparently you can on the Tmo plan.

If you don't mind an external device there is also TruConnect which is pretty cheap ( sprint MNVO ) and can package the deal with a MiFi ( $5/month + $.039/MB ) works out pretty well assuming you have sprint native coverage.

Gophone data packages have rollover and all have 30 day expirations.
$5/10mb $15/100 mb $25/500 mb

Att Prepaid Broadband to go have shorter times and no rollover.
$15/100 mb/24 hours $30/300 mb/7 days $50/1gb/30days.


Frankly the gophone data packages are a better deal. Can they be used on an Att branded or Att 3G frequency compatible unlocked modem instead of the Prepaid broadband plans. If so, how? Thanks.
