Although it’s not 100% clear, it looks like T-Mobile has decided to reduce the amount of Internet data allowance each handset has to quite a low level (in fact, one of the low levels available from the main networks). Whereas before T-Mobile had a high fair usage limit (often 3-4GB before they got upset and warned users), or stated a limit around 1GB (but without enforcing it), they have just published this information (here) stating that the limit is now 500MB across all contracts (old and new) as from 1 Feb 2011. When other networks have tried this in the past, they have often accepted that it warrants a change in the T&Cs, and allowed people to cancel contracts early, however, we are hearing that T-Mobile are not letting people out of contracts over this change.
Let’s be clear, for many users this simply won’t be a problem;recently told me that over two thirds of their users use some of the 150MB data allowance provided whenever you topup, but most did not exceed that limit, nor needed to buy any additional internet allowances, so it may well equally be that many T-Mobile users will never reach the new lower limits, however, there will be some who use devices such as Android phones, which are constantly syncing data (email, calendars etc.) and using online navigation solutions (such as Google Maps), and uploading photos or videos directly from the handset who will find the new lower limit a struggle.
Other networks seem to offer 500MB on their lower tariffs, moving up to 750MB and then 1GB for the higher tariffs (or specific tariffs, such as for the), so this does seem to be a rather low limit across all tariffs, and there are still statements on the T-Mobile website implying that there are a range of allowance for Apple devices.
In fact, if you head to the Fair Use Policy pages (here), these still list figures of up to 3GB as applying to new contracts, so it’s definitely not clear what rates will apply for someone taking out a contract today, but it’s fair to say that it looks like T-Mobile may be reducing everyone’s allowances from next month.
T-Mobile have privately let me know that even if you go through the 500MB limit (and they’ve said very few customers do use more than that on a monthly basis), you should still be able to browse the web and read email even at the limit. It’s ironic that T-Mobile have introduced these new lower limits only a few weeks afterstarted to remove limits from some of their high end tariffs…
