AT&T says it will begin selling two new 4G products, the USBConnect Momentum 4G and Mobile Hotspot Elevate 4G, Sunday.

Finally — ATT has some 4G hotspots.

For $50, customers will be allowed up to 5 gigs of data monthly. Every extra gig will cost you 10 bucks. According to the press release, the two devices are the only ones in the United States to default to 4G/HSPA+ if you move outside of an LTE coverage area.

AT&T will begin deploying its 4G LTE network in five markets (Atlanta, Dallas, Houston, Chicago, & San Antonio) this summer. Its first 4G phone, the HTC Inspire 4G, had a successful launch in early February, but it soon became clear that AT&T’s HSPA+ 4G speeds weren’t up to par. The company has continued to expand its network, going so far as to proposemerging with T-Mobile to bolster its system.

So what did I mean by AT&T “finally” getting some 4G hotspotting action?

Other 4G hotspot options on the market include Clear’s WiMax iSpot, which runs on Sprint’s network for 3Mbps to 6Mbps down, for up to four hours. iSpot costs $100 plus a data plan with Clear that runs as little as 20 bucks a month. Clear also has a USB alternative, the Clear 4G+ Mobile USB, which can be had for $115 plus the price of a data plan.

Novatel also has a 4G WiMax MiFi hotspot that’s supposed to provide 30Mbps down and 10Mbps up, as well as MiFi units for LTE and HSPA networks.

And then there’s the Samsung LTE hotspot that works with Verizon’s speedy 4G network. And T-Mobile’s 4G hotspot will run you $125 to take advantage of their HSPA+ network.

AT&T’s existing hotspot, the USBConnect Adrenaline, will get an upgrade to support LTE on Aug. 26. You’ll be able to get the USBConnect 4G for $49.99 and the Mobile Hotspot Elevate 4G for $69.99 on Sunday, both with a two-year contract.

The USBConnect Momentum 4G modem and Mobile Hotspot Elevate 4G will provide portable 4G access to AT&T subscribers.
