Kolet eSIM Data Plans for Thailand

Kolet does not provide a truly unlimited eSIM plan for Thailand. All of its Thailand‑specific plans list a specific data cap, such as 5 GB per day or 20 GB for a month. Plans with “UNLIMITED” in the name still have a hard limit of 5 GB per day and switch to a reduced speed of 1024 kbps once that daily allowance is reached. Instead, travelers can choose from fixed‑data bundles, for example a 20 GB package valid for 30 days or a 10 GB package also valid for 30 days, both of which deliver full‑speed 5G service during the 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.
