What a Carr’s Telecom eSIM costs
The cheapest published plan on the Montserrat travel eSIM is $8.00 for 1 GB valid 7 days. A 2 GB / 15 day plan is $15.00, a 3 GB / 30 day plan is $21.00, and a 5 GB / 30 day plan is $32.50. There is no unlimited SKU on this product, so a heavy stay is bought as buckets. Compare the 3 GB and 5 GB plans before you commit: the step from 3 GB to 5 GB costs $11.50 for two extra gigabytes, which is the worst value step on the product. If you will be on hotel Wi-Fi most evenings, the 3 GB / 30 day plan is the sensible one.
Network
The plan is sold under the operator name Carr’s Telecom and the supported country is Montserrat. The product page publishes the speed as 4G. That is the figure to plan around, and real speed still depends on the mast, the handset, and the carrier Fair Usage Policy. Montserrat is covered as one country on this plan. The island is small, roughly 16 km from end to end, and the populated middle of it covers the administrative centre at Brades, the main settlement and ferry landing at Little Bay, and the villages of Salem, St. Peter’s, and Geralds. Montserrat is a British Overseas Territory, and this is not a UK plan: a UK SIM or a UK eSIM does not cover it. It does not cover Antigua, St Kitts and Nevis, or Guadeloupe either, so the ferry to Antigua needs its own plan.
How much data you actually need
Maps, chat, and boarding passes sit inside 1 GB for a short stay. Photos and short video push a week toward 3 GB. A month of guesthouse Wi-Fi plus mobile backup is the 3 GB or 5 GB / 30 day plan. Hotspot use burns the allowance faster than the phone alone, and on an island this size you will often be the one hotspotting a laptop.
Unlimited data
This product has no unlimited plan. Every option is a fixed bucket: 1 GB for 7 days, 2 GB for 15 days, 3 GB or 5 GB for 30 days. If you need a lot of data, the 5 GB / 30 day plan at $32.50 is the ceiling on this product, and anything beyond that has to be bought as a top-up or a second plan.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Carr’s Telecom line. iPhone: Settings, Mobile Data, pick the travel line. Android: Settings, Network, SIMs, set mobile data to the travel eSIM. Do this before you leave the airport Wi-Fi.
Arrival and transit
There is no long-haul flight to Montserrat. Most visitors connect through Antigua (ANU) and then take the short regional hop into John A. Osborne Airport (MNI) at Geralds, or the ferry from Antigua’s Jolly Harbour to Little Bay. Install the eSIM on hotel or home Wi-Fi before the flight, then switch the data line on after you clear arrivals. You do not need a local shop or a passport photo for this plan.
Install
- Buy the plan and open the QR code in the order email while you still have Wi-Fi.
- On the phone, add an eSIM and scan that code. Label the line “Montserrat”.
- After landing, set mobile data to that line and leave your home number on for texts.
Phone compatibility
The phone must be carrier-unlocked and eSIM-capable. iPhone XS and later, and recent Samsung Galaxy and Google Pixel models, qualify. A locked handset will not take the QR code. Check the lock status with your home carrier before you pay.
FAQ
Q1: How much is the cheapest Montserrat eSIM?
$8.00 for 1 GB, valid 7 days, on the Carr’s Telecom plan.
Q2: Which operator is on the plan?
Carr’s Telecom. The supported country is Montserrat.
Q3: Does it include calls and SMS?
No. It is a data plan, with voice calls only through apps such as WhatsApp or FaceTime. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
No. The product page lists the speed as 4G. Real speed still depends on coverage and the Fair Usage Policy.
Q5: Can I install it after I land?
Yes, if you can reach Wi-Fi. Installing before the flight is simpler, because the QR download needs a connection, and the airport at Geralds is small.
Q6: Will it work outside Montserrat?
No. This plan is for Montserrat only. Antigua, St Kitts and Nevis, and Guadeloupe each need their own plan.
Q7: Is there an unlimited option?
No. There is no unlimited SKU on this product. The largest bucket is 5 GB over 30 days at $32.50.
Q8: Can I share it as a hotspot?
Yes, within the data allowance. Hotspot traffic counts against the same gigabytes, and heavy sharing can hit the Fair Usage Policy.
Q9: What if the QR code fails?
Use the manual activation code in the same email. The phone still has to be unlocked.
Q10: When were these prices checked?
October 2026, against the published variation prices on travelydata.com.
Bottom line
For a week in Montserrat, the $8.00 / 1 GB Carr’s Telecom plan is the one to start with, and it is enough if you stay on guesthouse Wi-Fi. Take the 3 GB / 30 day plan at $21.00 for a longer stay or if you will be hotspotting. The published speed is 4G and there is no unlimited option, so pick a bucket that matches how much you will actually use.
