Kolet eSIM Data Plans for Thailand

Kolet does not provide a truly unlimited data eSIM for Thailand. Their plans labelled “Thailand UNLIMITED” give travelers 5GB per day at full speed and then throttle to 1000kbps once that daily amount is used. Travelers who need more data without throttling can choose one of Kolet’s fixed‑data plans, such as the Thailand 20GB for 30 days or Thailand 10GB for 30 days, which offer the full data allowance at full speed for the entire validity period.

Kolet does not provide any Thailand eSIM plans that include a phone number or SMS capability. Travelers using Kolet for Thailand will receive only a data‑only eSIM, which gives high‑speed internet access but no traditional calling or texting services.

Instead, users can rely on internet‑based voice and messaging applications such as WhatsApp, Telegram, or iMessage for communication. However, some destinations may restrict or block certain VoIP services, so it is advisable for travelers to confirm that the applications they intend to use are accessible in Thailand before purchasing a Kolet plan.

Kolet offers 13 single‑country plans and 10 multi‑country plans for Thailand. The available plans range in price from $3.99 to $121.50 and provide between 1 GB and 20 GB of data. Some plans are fixed‑data, giving a set amount of data for the entire validity period, while others are daily‑cap plans that reset each day.
