Mobily is one of the networks your eSIM may use in Saudi Arabia. Here is who actually decides which network you get, and what to do with that.
Quick answer
Mobily runs commercial 5G in Saudi Arabia on the 3.5 GHz band (n78, 100 MHz) under MCC-MNC 420-03.
| Item | Mobily |
|---|---|
| LTE (4G) | B3, B41 |
| 5G NR | n78 |
| 5G launched | Live |
| Network code (MCC-MNC) | 420-03 |
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 Mobily 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.
Mobile networks in Saudi Arabia are licensed, and their spectrum assigned, by the Communications, Space and Technology Commission (CST). 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.
From the supplier record behind each package, 46 of the 71 plans we currently sell for Saudi Arabia declare Mobily 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.
| Network | LTE bands | 5G bands |
|---|---|---|
| Mobily | B3, B41 | n78 |
| STC | B1, B3, B20, B40 | n78 |
| Zain KSA | B1, B3, B8, B41 | Not verified |
A band shared across networks is one a single phone can use on all of them.
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Mobily is weak where you are, try selecting STC or Zain KSA manually in the network settings, and keep data roaming on for the eSIM profile.
46 of our plans name Mobily 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.
At least one of these, LTE: B3, B41; 5G: n78. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Yes. Mobily has run commercial 5G, 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.
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.
