T-Mobile vs travel eSIM for South Africa
T-Mobile offers three tiers for South Africa: free at 128 kbps (unusable for most), Go5G Plus with 5GB free high-speed (good for light users on premium plans), and International Pass at $10/day (expensive for longer trips). A travel eSIM at $2.87 for 1GB runs at full LTE speed with no daily cap beyond the total plan allowance. For a 10-day trip, the International Pass costs $100.00 versus $2.87 for the eSIM. The T-Mobile free tier is the only carrier option that costs less than an eSIM, but the 128 kbps speed makes it impractical for normal phone usage.
