Boost Mobile SIM only plans offer a wide range of affordable prepaid mobile SIM plans featuring services such as unlimited calls and texts, unlimited standard international calls, as well as substantial monthly data allowance.
Can I buy a SIM card and keep my number?
Yes, you can buy a new SIM and keep your number. Simply head to activate and click ‘keep existing number.’
How do I choose a good SIM card?
