AT&T has added salt to consumers’ wounds; earlier the carrier raised its smartphone early termination fees (ETFs, charges levied when a customer wants to opt-out of a service contract early) from $150 to $325, they’ve now raised their smartphone early upgrade fees, as well. Those fees are for those who want to upgrade their smartphones to a new model earlier than allowed.

The change excludes the iPhone, but covers all other smartphones. Originally, the fee was $75; with the change, it’s now $200. AT&T didn’t exactly publicize the change with a press release: BGR found out about the change, which began on Oct. 3rd, via a leaked memo.

We confirmed the change by calling an AT&T support representative. All they would say is that the early upgrade fee has risen to $200, and was “recently” changed from the earlier $75.

This is just another way for carriers to make sure they lock consumers in, not just into contracts, but into devices. As we said, earlier this year AT&T raised its ETF; last year, Verizon doubled its ETF from $175 to $350.
