Is using SouthESIM cheaper than my AT&T / T-Mobile / Verizon roaming plan?

In almost all cases, yes, SouthESIM offers a much more budget-friendly option! US carriers often charge $10-$14 per day for international roaming, which can quickly add up to a significant cost for even a short trip. With SouthESIM, you purchase a prepaid data plan for a one-time fee. For the cost of just a couple of days of US carrier roaming, you can often get a SouthESIM plan with enough data for your entire trip, saving you money to spend on more adventures!
