Does using a duplicate sim (same line on two phones, iPhone + non-digits app supported phone) cost extra?


    I have an iPhone 7 on a TMBO @ Work plan and currently use digits on my computer. I also have a BlackBerry Bold 9900 that I am thinking about switching back to. I already have sim cards for both, however, only the iPhone is active. If I want both sim cards to be active would that incur an extra charge. Also, because I would be on a BB7 device I would need a BIS plan. Would BIS prevent digits from working?
