T-Mobile may be joining rivals Verizon and AT&T by introducing an $35 charge for all new postpaid activations and upgrades, according to The T-Mo Report and some Redditors.Before, the Uncarrier charged activation fees only if you received in-store customer support for new activations, with online orders exempt.T-Mobile has always tried to separate itself from regular telecoms, but charging customers for essentially nothing doesn't sound very Uncarrier-like, if the reports are accurate.When that deal was finalized, T-Mobile said things would be "better for customers," but constant activation charges would definitely not be better.Worse, it appears to be justifying the new fee in a dubious way, saying it's "simplifying" the system to bring a "more consistent and straightforward experience for customers.""
