If a Sprint contract is up, and we're now on a month-to-month type schedule, can we add a device without incurring another 2 year contract?

I don’t think so. They would always look for an excuse to tie you in a contract, not the other way around. They don’t make their “bigger” money out of selling the devices, it’s in the contracts. They would give you a free phone to get you to sign a contract which would pay for the phone and the service many times over.

If you buy a phone outright at T-Mobile, you don’t have to sign a contract.

It really depends on how they handle adding the new phone to your plan. It seems like some companies like to renew your contract anytime you make changes to your plan and adding a new phone/line would definitely be a change. If you aren’t having any luck with the people at the store, maybe you should trying calling Sprint directly and speak with someone there or try another store. I’ve realized that going to the stores for cell phone issues can be really hit or miss sometimes with how helpful the salespeople are.

I am sure you can under the right conditions with the right contact.

Remember, their goal is to keep you as a customer for as long as possible. This means trying to tie you to a contract.

Shop around now and make a choice while you can.

If you want to get the phones at the lower price Sprint will require anther 2 year contract. It sucks. I am with Sprint, but I absolutely hate the contract BS, and that I am supposed to really think my phone is worth $600 not $100. Whatever.

I am willing to pay the ticket price. Or even bring a used device. Any added thoughts with this specified information?

@squirbel Then you should be able to continue month to month, they just need to set up the new phone, to activate it.
