Hi Warren, Apologies for the delay in response. Yes we do have a "bring your own device" that works with Prepaid! Since there's a handful of compatible smartphones, if you would like me to check whether a specific smartphone is compatible, please let me know and I can. Customers who bring their own device have to purchase an MTS prepaid SIM card (as long as it’s compatible) to activate on the MTS prepaid wireless network. Just a note that unfortunately customers with a pre BB10 software BlackBerry are ineligible to activate their device on Prepaid, as BlackBerry’s must have BB10 or higher. Thanks for the question.
