T-Mobile USA threw the cat among the budget pigeons back in April with its Simple Starter plan, a $40 tariff promising no data overage fees, and now the carrier is adding an upgrade option for those wanting more internet access. Until now, Simple Starter included 500 MB of LTE data each month, but for $5 extra T-Mobile will bump that up to 2GB.
The add-on only affects data use, not anything else about the plan, and doesn't introduce any minimum agreement length.
The existing unlimited talk and text allowances are still included. As before, once subscribers hit their data limit they'll be cut off from browsing, rather than charged fees.
It's those fees which the plan was intended to challenge, and which outspoken T-Mobile CEO John Legere has criticized strongly in the past. The plan isn't without its limitations, however, with no provision for international texting or roaming.
The $5, 2GB add-on will be available to new and existing Simple Plan customers from September 3rd, T-Mobile says. It's described as a "limited offer," however, and there's no indication of how long it may be offered for.
