Flow Cayman and travel eSIM in Cayman Islands
Flow Cayman is one of the networks your eSIM may use in Cayman Islands. Here is who actually decides which network you get, and what to do with that.

Quick answer
- 17 of the 17 Cayman Islands plans we sell name Flow Cayman as a reachable network, at 4G and 5G.
- Flow Cayman runs LTE on B2, B17 and 5G on n78; your phone needs at least one of them.
- Travel plans connect by roaming, so no plan can promise one specific network.
Flow Cayman in brief
Flow launched 5G in the Cayman Islands in June 2024, using 200 MHz of 3.5 GHz spectrum (band n78).
We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.
Flow Cayman's bands and technology
| Item | Flow Cayman |
|---|---|
| LTE (4G) | B2, B17 |
| 5G NR | n78 |
| 5G launched | 2024 |
| Network code (MCC-MNC) | 346-140 |
Checked against the sources on 2026-10-12. Only the bands a source confirmed are listed; the network may run others too.
An eSIM can only use Flow Cayman if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.
Who licenses Flow Cayman
Mobile networks in Cayman Islands are licensed, and their spectrum assigned, by the Utility Regulation and Competition Office (OfReg). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.
The plans on our shelf that name Flow Cayman
From the supplier record behind each package, 17 of the 17 plans we currently sell for Cayman Islands declare Flow Cayman as a network the profile can reach, at 4G and 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.
A plan naming Flow Cayman means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order is the supplier's, and the signal where you stand decides.
Why plans do not name a fixed network
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Flow Cayman is weak where you are, try selecting Digicel Cayman manually in the network settings, and keep data roaming on for the eSIM profile.
FAQ
Will my eSIM definitely connect to Flow Cayman?+
17 of our plans name Flow Cayman as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
Which bands does my phone need for Flow Cayman?+
At least one of these, LTE: B2, B17; 5G: n78. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Does Flow Cayman run 5G, and will my plan get it?+
Yes. Flow Cayman has run commercial 5G since 2024, on n78. A travel plan only gets it when the plan permits 5G, your phone supports one of those bands, and you are inside 5G coverage. Miss any one and you fall back to 4G.
How do I see which network I am on?+
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
