yaySIM for Southeast Asia FAQ
Does yaySIM offer unlimited data eSIM for Southeast Asia?
yaySIM does not provide any unlimited data eSIM plans for Southeast Asia. The available offerings are fixed‑data packages, such as the 50GB plan that is valid for 180 days and covers Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam, or a 20GB plan that is valid for 30 days and covers the same core group of countries. Because these plans have clear data caps, travelers who need large amounts of data may find the fixed‑data options more cost‑effective than attempting to use an unlimited service, which is not offered by yaySIM in this region.
Does yaySIM offer Southeast Asia eSIM with phone number and SMS?
YaySIM does not offer any Southeast Asia eSIM plans that include a phone number or SMS capability. All available plans are data‑only, so travelers cannot receive or send carrier‑based voice calls or text messages. However, common VoIP applications such as WhatsApp, Telegram, and iMessage can typically be used over the data connection to make calls and send messages, although some destinations may block or restrict access to particular apps; users should verify app availability in the country they plan to visit before making a purchase.
What countries are covered by yaySIM's eSIM plans in Southeast Asia?
Plans such as AS‑7_0.5_Daily cover Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam; SGMYVNTHID‑5_1_Daily covers Indonesia, Malaysia, Singapore, Thailand, and Vietnam; AS‑21_0.5_Daily covers Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam; AS‑12_0.5_Daily covers Indonesia, Cambodia, Malaysia, Singapore, Thailand, and Vietnam; AS‑20_1_7 covers Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam; GL‑120_1_Daily and its 7‑day variation cover Indonesia, Malaysia, Philippines, Singapore, and Thailand; and GL‑139_1_7 covers Brunei, Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam.
