Frequently Asked Questions
Does ZenSim offer unlimited data eSIM for Thailand?
ZenSim does not offer a truly unlimited high‑speed data eSIM for Thailand. The plans marketed as “Unlimited” provide only 3 GB/day of high‑speed data; once the daily limit is reached the speed is throttled, so the label does not mean no data cap.
Instead, ZenSim sells fixed‑data plans that give a set amount of high‑speed data. For example, the Thailand 20 GB plan is available for 10 days or 30 days, and the Thailand 10 GB plan is offered for 10 days. These fixed‑data options may be more cost effective for travelers who do not need a large daily data allowance.
Does ZenSim offer Thailand eSIM with phone number and SMS?
ZenSim only offers data‑only eSIM plans for Thailand and does not provide a local phone number or SMS capability. Travelers can still communicate using VoIP services such as WhatsApp, Telegram, or iMessage over the data connection.
How many data plans does ZenSim offer for Thailand?
ZenSim offers eight single‑country plans and eight multi‑country plans in Thailand. Across all plans the data caps range from 3 GB to 20 GB, the prices continue from $13 to $70, and validity periods span 10 to 30 days. Some plans feature a fixed data amount while four provide a daily data cap, and all included plans allow tethering.
