Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Southeast Asia?
Firsty offers an unlimited data eSIM for Southeast Asia through its Firsty Free plan, which is valid for 1 day and priced at $0.00โฏUSD. The plan includes advertising and notes that, while data usage is unlimited, speeds may be throttled and are capped at a maximum of 256kbps. Because a Fair Usage Policy is applied, heavy usage may lead to further speed reductions; travellers who want to confirm how FUP may affect their experience should contact Firsty directly for details.
Does Firsty offer Southeast Asia eSIM with phone number and SMS?
Firsty does not provide eSIM plans for Southeast Asia that include a phone number or SMS support. The offerings in that region are limited to data-only subscriptions, so users will not receive a local or international dialing code for voice calls or SMS.
Travelers who need to make calls or send messages can rely on VoIP applications that use the data connection, such as WhatsApp, Telegram, or iMessage, to communicate without a traditional phone number.
