Best Answer: Yes, you absolutely can keep your number when switching wireless carriers. DO NOT cancel your service with T-Mobile. Simply go into a Sprint store and give them your T-Mobile phone number and account number.
They will then port your number over from T-Mobile and you will be able to keep it. Once your number has been ported, it automatically cancels your account with T-Mobile. If you cancel your service through T-Mobile first, you will lose it forever! Source(s): I am a retail sales consultant with AT&T.
