Pricing Grid Comparison

DataConnect

DataConnect plans are for tablets, laptops, mobile hotspots/routers, and gaming devices. Access to AT&T's domestic public Wi-Fi hotspots is included. 

These are the options available for LTE and 5G devices:

• 15GB for $60/month
• 35GB for $85/month

There is a $10/month discount if auto payment and e-billing is selected. This plan does not use shared data - a data allotment must be purchased for each device. Once the data limit is met, additional data will be automatically added at $10/2GB. 

Connected Car & RV

These plans are offered for vehicles with built-in hotspots, such as GM's OnStar, Airstreams and Ford's SYNC systems. They also offer an aftermarket OBD-II device that is eligible for in vehicle usage only. More information is available on the AT&T Connected Car website.

Plan Options:

• Connected Car Unlimited Data: $20/month per car, for up to 3 cars
  • Network Management after 22GB
  • Includes roaming into Canada
• HarmanSpark (or other OBD-II devices)
  • 5GB or 10GB plans
• Add to an existing Mobile Share Plan for $10/month

Wireless Internet (**Top Pick**)

AT&T Wireless internet provides a traditional telephone line and data and are only eligible on AT&T's Wireless Internet devices (which are a combo cellular embedded router with phone jack). These plans can not be activated on other hotspots or routers.

While intended as a home or business internet solution, the plans and devices are mobile-friendly. 

Plan Options:

• 100GB for $100/month
• 50GB for $60/month

Info on these plans can be found here: AT&T Wireless Internet

Tablet Unlimited Plan (**Top Pick**)

Tablets can be enabled as single lines of service at full price on AT&T's "unlimited" plans or added on to unlimited smartphone plans for just $20/month. However, when added as a line of service, they come with the features of the 'Starter' plan (480p video, no hotspot data, and always subject to network management.)

However, there's also a little known plan for just $20/month that includes unlimited data on tablets that can be purchased ala carte without other lines of service. It's assumed this plan is really there for adding on to accounts that have already reached their 10-line limit - but it still can be activated without other lines of service.  

The plan has network management after 22GB of usage, and it's unconfirmed if any high-speed mobile hotspot is included. 

It is listed in AT&T's system as  "Unlimited For iPad" and "Unlimited for Tablet". You'll have to find a rep who knows about this plan over the phone or in a corporate store to activate it on a cellular-enabled tablet. 

This is a post-paid plan for tablets only, and there is a $30 activation fee.

There are further notes in the member section below on this option. 

Mobile Share Data Plans (In-Store Only)

These plans include a shared data amount to share with up to 10 data-only devices. Smartphones are not eligible. Eligible devices include tablets, laptops, routers and hotspot devices.

There is a monthly plan charge plus a monthly device access charge for each data-only device on your account that will be using the plan. Monthly device access charges are determined by the type of data-only devices you add to the plan. Laptops, netbooks, and hotspots are $20/month, and tablets and gaming devices are $10/month.

Monthly plan charges are as follows:

Business Plans

AT&T Business offerings for smartphones and data-only devices that may be an option for those who have a qualifying business. These plans come with some major advantages over AT&T's consumer plans - such as 100GB of high-speed mobile hotspot off of a smartphone for the same price.
