Find answers to commonly asked questions about domestic data roaming.
Domestic data roaming occurs when you travel outside of T-Mobile's network coverage, using wireless data from another carrier. There's no added charge for the service. You'll receive a usage alert when you've reached 80% of your monthly domestic data roaming usage; then you'll receive a second alert when you've reach 100%.
This depends on your data plan option. In general, the larger your full-speed data allotment, the more domestic data roaming you have access to each month. This means that if you reach your designated domestic data roaming allotment for the month, you have the option to upgrade to a larger full-speed data option either temporarily or permanently if you want more access off the T-Mobile network.
