For a limited time, Boost Mobile is offering new customers unlimited 5G data with unlimited talk/text for just $25 per month (opens in new tab). That’s 50% off its regular $50/month price and one of the least-expensive unlimited 5G data plans 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. Boost doesn’t require service contracts and the prices you see include taxes and fees. The service works with most unlocked GSM phones.
