Does my phone support eSIM?
On an iPhone, open Settings → Mobile Service (on some iPhones: Mobile Data): if there is an Add eSIM option, the phone has an eSIM. On Android, look for an option to add an eSIM in the SIM settings (Samsung: SIM manager → Add eSIM, in Samsung’s January 2025 guide SIM card manager → Add mobile plan; Pixel: Add SIM). Can’t find it? Look up your model in the list of eSIM-compatible phones.

Frequently asked questions
How much does a day of mobile data cost in Sri Lanka?
On plans with a fixed data allowance, £0.17 to £0.63 a day in Sri Lanka: 3 GB for 30 days at £4.99 is the lowest daily price, 20 GB for 30 days the highest. The plan that costs least for the whole trip: for 7 days, 1 GB at £0.43 a day; for 15 days, 2 GB at £0.27 a day; for 30 days, 3 GB at £0.17 a day. Unused days are not refunded.
Which network does the eSIM use in Sri Lanka?
Two partner networks: Dialog (4G) and Hutchison (4G). The profile joins whichever is available; you don’t choose the operator by hand.
What if the eSIM doesn't work when you land in Sri Lanka?
Check, in this order: data roaming is on for the eSIM line, the eSIM is chosen as the line for mobile data, and aeroplane mode is off. The APN sets itself on this plan, so leave it as it is. Give the phone a few minutes to register on Dialog and Hutchison; that first registration is what starts the plan’s days. Still no connection? See what to check when the eSIM has no signal abroad.
General questions have their own pages: how card payment works, refund policy, how to install an eSIM and help and FAQ.
Prices come from our partner operator’s catalogue and may change; the amount at the moment of payment applies. We are not a mobile operator: network access is provided by the partner operator, under the plan’s terms. See the terms and the refund policy.
