Following a number of new initiatives launched last week including its new Simple Starter plan and new perks for tablet users, T-Mobile issued a press release today calling for an end to overages and urging consumers to sign a petition for AT&T, Sprint and Verizon to do the same.

Traditional wireless plans start with a low monthly fee for a fixed amount of domestic minutes, texts or data.  Once consumers go over those limits – even by a little – they’re hit with dramatically higher rates and extreme penalties.  These plans seem purpose-built to drive customers over that invisible line into massive overage charges.

In the press release, the carrier noted it will end all domestic overages in starting in May for the June billing cycle (something we thought it was doing since the beginning of Uncarrier?). The wording also sounds a lot like it could continue to charge overages for international use.  T-Mobile’s new Simple Starter plan does not include the free international perks it unveiled for other plans last year, so it looks like the carrier is giving itself some room to continue charging overages for international use in some cases.

T-Mobile has been doing a lot of talking about ending overages, and its approach might be slightly more transparent than the other guys, but at the end of the day an overage is an overage and even T-Mobile charges some customers for more data. It’s new Simple Starter plan for example which caps at 500MB for LTE data, will force users to purchase $5/day or $10/week “additional data sessions.”
