Following our coverage last week, where we broke ground on how to (legally) use the Nokia 3555 as a mobile broadband card on T-Mobile Sidekick Prepaid, T-Mobile has decided to shut down all access to non-Sidekick devices on T-Mobile prepaid data.
The Sidekick Prepaid Plan is a $1/day data option that offers unlimited data, plus unlimited SMS and MMS. It is far cheaper (arguably infinitely cheaper) than AT&T GoPhone’s rate of 100 MB for $20. The plan has been well-known since its inception for being used on a broad range of devices other than Sidekicks; iPhone and T-Mobile’s G1 being the two most popular in the enthusiast community.
T-Mobile representatives claim that non-Sidekick phones were never intended to use Sidekick Prepaid Data, even going as far as to refer to the offering as a “breach of security.” T-Mobile did agree however that users were not abusing the network, in accordance with FCC regulations and recent rulings.
Customers who purchased the Nokia 3555 for this use should return the phones, in accordance with T-Mobile’s return policy.
However, there are some customers who are now worse off; iPhone 2G and 3G customers alike now have no unlimited prepaid data plan for their phones.
