GlobaleSIM does sell Sri Lanka eSIM plans that include a phone number and SMS services. These plans range in price from $4.00 to $31.50 USD and validity from 7 days up to 30 days, with data caps between 1 GB and 20 GB. Each Sri Lanka‑specific plan uses the dialing code +1, allows both inbound and outbound voice calls, and supports inbound SMS only.
There are also Central Asia plans that cover Sri Lanka together with 12 additional countries. They have the same +1 dialing code, voice, and inbound SMS capabilities, but the prices are higher for equivalent data allowances. Travelers who need a local number for inbound calls and messages, or who require outbound SMS, should confirm the exact features directly with GlobaleSIM before finalizing a purchase.
