I've bought a family member a Rain sim card - which will be delivered directly to them - and to reduce the trouble of getting it RICA'd, I'm just going to use my current Rain profile which already has a sim card on it. If I activate a second sim card, will it still get the 7-days free unlimited data - or is there some kind of limit per account? (I know there's a limit on the total number of sims on one account, but not whether it impacts the 7-days free period)
