Can this offer be used to upgrade a device? Also what's the maximum payments that can be made?
No maxmium AFAIK, upgrades are tricky because sales charges might code differently, I'm not sure. But (assuming you have credit allowance with t-mo) you can finance a device and then it gets billed to your account.
But can't I bill the device to my account or upgrades require a one time payment (not planning on financing)? Thanks
