Thumb Cellular only requires your account number and PIN to port out. They do not offer any online accounts, so you will have to contact Thumb Cellular customer service number or visit a local care center in Michigan to get your account number and PIN.
Your 11 digit phone number (1-***-***-****) is the account number for T-Mobile Prepaid. The passcode is your 4-digit PIN number (the same PIN used when calling customer service). If you don’t have a PIN you can set one up by calling 611 from your T-Mobile phone and saying “no” when it asks you if you want to refill and then choosing “Manage my account” followed by “change my account PIN”. If you forgot your PIN number or need other help call the porting department.
Customer gets a paper statement that will have billing address as their system has it written, along with the account number (which is the phone number). Account PIN is not listed on the billing statement, but will be a four digit number. If an existing customer needs to call for support, the 10-digit phone number and four digit PIN number is required by the automated system.
