The verdict, & two little voices
Should you actually get Prepaid Unlimited (Online Only)?
The editor weighs in — flanked by the optimist on her shoulder and the cynic on the other.
“$25 for AT&T's coverage, no contract, no credit check. Messaging and light browsing work fine.”
“3 Mbps is a hard ceiling, not a congestion slowdown. Every video call and HD stream will feel it.”

Our review
The AT&T Prepaid Unlimited (Online Only) is a $25/mo prepaid plan sold exclusively through AT&T's website, not in stores.
The defining characteristic is how it handles data speed: the plan doesn't provide full 5G or LTE speed. Instead, data is capped at a max of 3 Mbps at all times, regardless of network conditions - and after 30 GB, the cap drops further to a max of 1.5 Mbps. At 3 Mbps, basic browsing and SD video work adequately; video calls and HD streaming will struggle.
No hotspot is included in the base plan, though it's available as an optional $10/mo add-on for 5 GB. Standard-definition streaming. AT&T ActiveArmor is included.
New single-line only.
What we love
- $25/mo on AT&T's network with no credit check and no contract
- 30 GB at the 3 Mbps speed cap before further reduction
- AT&T's coverage footprint - particularly strong in the South and rural areas
- Hotspot available as an optional $10/mo add-on
- No annual commitment
What we don't
- Speed is capped at 3 Mbps at all times - slower than what AT&T's 5G is capable of and slower than a typical home broadband connection
- After 30 GB, speed further reduces to a max of 1.5 Mbps
- No hotspot included - requires the $10/mo add-on for 5 GB
- Standard-definition video only
- Online purchase only, not available in stores
- New single-line required
- The $10/mo hotspot add-on brings the total to $35/mo - Visible at $25/mo taxes-in delivers a faster connection without the same caps

Frequently asked questions about Prepaid Unlimited (Online Only)
What features does Prepaid Unlimited (Online Only) include?
The plan includes unlimited data at a max of 3 Mbps (dropping to 1.5 Mbps after 30 GB), unlimited voice and text, and AT&T ActiveArmor. No hotspot included - 5 GB hotspot is available as a $10/mo add-on. Standard-definition video. Online purchase only with a new single-line activation. No annual contract. No autopay discount listed - the $25 is the base monthly price.
How much data, talk, and text does Prepaid Unlimited (Online Only) include?
Data is unlimited at a max speed of 3 Mbps - that's a hard speed cap, not just a throttle that applies during congestion. At 3 Mbps, standard-definition video and basic browsing work. After 30 GB, the max speed drops to 1.5 Mbps, which handles messaging and light browsing adequately. Voice and text are unlimited.
What is the network speed on Prepaid Unlimited (Online Only)?
Data is capped at a maximum of 3 Mbps at all times - this isn't deprioritization during congestion, it's a hard speed ceiling regardless of network conditions. At 3 Mbps: standard-definition (480p) video streams adequately, basic web browsing is workable, video calls will be choppy, and anything requiring sustained fast speeds (large downloads, HD streaming) won't deliver. After 30 GB, the ceiling drops to 1.5 Mbps.
Does Prepaid Unlimited (Online Only) include mobile hotspot?
No hotspot is included in the base plan. The $10/mo add-on provides 5 GB of hotspot data. Adding the hotspot brings the total monthly cost to $35/mo.
What happens if you exceed your data on Prepaid Unlimited (Online Only)?
No overage charges. After the 30 GB threshold, speeds drop to 1.5 Mbps rather than extra fees. Voice and text have no limits.
Does Prepaid Unlimited (Online Only) require a contract?
No annual contract. Month-to-month prepaid with no credit check required. Cancel at any time.
