Already a T-Mobile customer?

If you already have active T-Mobile service and your question is about billing, an outage, a speed problem, or changing your plan, T-Mobile handles that directly and can resolve it much faster than we can. Call T-Mobile customer care at 1-800-937-8997 or dial 611 from your T-Mobile phone. We are an independent authorized retailer and do not have access to your T-Mobile account.

Stop hearing from us

To stop calls, texts, and emails, reply STOP to any text, tell any representative to add you to our do-not-call list, use the unsubscribe link in any email, or submit a request on our Do Not Sell or Share page. We honor requests promptly and always within ten business days.
