How old is your original account? ( 10gb plan) Does it earn $$ rewards or Public Points? Do you want to keep the phone #? If you have a $$ rewards account it's best to keep it or allow someone to take it over rather than cancel it. Phone. #'s are generally non-transferable between accounts. You can also suspend for up to 88/89 days so that you only need to pay for one account's services at a time allowing for a little overlap in 30 day service.
You can schedule a change plan on next renewal for your original plan in your account. Either to a larger data plan or to a lower priced plan like the $15 plan.
I actively seek rewards accounts for low and fixed income individuals if you wish to "pay it forward" with your original account feel to contact me via private message . 😀
