Customers report T-Mobile no longer allows locked phones on MVNO networks
You'll have to pay your T-Mobile phone off fully now
T-Mobile has made some changes to its network, specifically where locked phones are concerned. Now, you'll no longer be able to use a locked T-Mobile phone on an MVNO (Mobile Virtual Network Operators) using T-Mobile's network. At least, not without unlocking it.
