Unitel STP in brief
Unitel STP is a mobile network operator in Sao Tome and Principe, and one of the networks a travel eSIM may reach through roaming. From the information we track, it runs 4G and LTE.
Why plans do not name a fixed network
Nearly every travel eSIM is a roaming product. The supplier holds agreements with one or more networks in the destination, and your profile picks between them by a priority order set inside the profile, not by the buyer. Two travellers on the same plan can end up on different networks in the same city.
| What decides the network you get | Who controls it |
|---|---|
| The supplier's roaming agreements | The plan's supplier |
| The priority list inside the profile | The plan's supplier |
| The bands your handset supports | Your device |
| Signal strength where you stand | Physical location |
| How congested the cell is right now | The local network |
This describes how roaming works in general; it does not cite any specific commercial agreement.

FAQ
Will my eSIM definitely connect to Unitel STP?+
Not necessarily. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are. Unitel STP is one of the networks operating in Sao Tome and Principe, not a guarantee attached to any particular plan.
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.
Does Unitel STP run 5G, and will my plan get it?+
From the operator information we track, Unitel STP runs 4G and LTE. Getting 5G in practice needs three things at once: the plan permits it, your device supports it, and the area has coverage. Miss any one and you fall back to 4G.
