Boost Mobile is offering 3 months of 5G data with unlimited talk/text for just $15 total (opens in new tab). That’s 66% off its regular $45/month price and one of the best Boost Mobile deals we’ve seen. It’s worth noting that the SIM kit and shipping are also free, which saves you an extra $15. Boost Mobile offers some of the best prepaid phone plans we’ve tested. Plans are generally affordable, flexible, and family friendly. Boost is a mobile virtual network operator. MVNOs provide cellular service using another carrier’s towers — in this case T-Mobile. Although Boost used to be owned by Sprint, the company was sold to Dish as a result of the T-Mobile-Sprint merger. While you can get Boost’s unlimited plans for just one phone line, family plans offers the best value. The first line of unlimited data will cost you $50 a month, but after that, each new line costs $30 per month (or $40 per extra line on Unlimited Plus). Boost doesn’t require service contracts and the prices you see include taxes and fees. The service works with most unlocked GSM phones.
