WiFi has become a booking criterion, just like cleanliness. A traveller often checks its speed before booking. Four solutions are available to you.
Which WiFi solutions for a holiday rental?
Each option meets a specific need, depending on the area and the number of properties. Here are the four families to know.
- Fibre or operator box: the most stable speed, subscribed to at the property's address.
- 4G or 5G box: a unit with a SIM card, with no works or technician.
- 4G/5G router with a data SIM: a one-off purchase, movable between several properties.
- Mobile tethering: a stopgap solution, not a fixed piece of equipment.
Mobile tethering quickly drains the phone's data and battery. Keep it for the unexpected, never for continuous guest hosting.
Can a box be moved from one property to another?
No, and this is a point that is often misunderstood. A fixed box stays tied to the address it was subscribed to. This applies to fibre as well as to an operator's 4G or 5G box. You cannot move the box from your main home to a rented property.
So, for a rented home, take out a dedicated subscription at its address. Only the router with a SIM card and mobile tethering are truly portable. This is a decisive criterion if you manage several properties.

What speed should you plan for your travellers?
Speed makes all the difference to the guest experience. Several people often watch several screens at the same time. So you need to absorb simultaneous streaming.
This is the comfortable speed for 4K streaming on several devices at once. Below 50 Mb/s in real terms, the experience degrades quickly.
Allow around 5 Mb/s per stream in Full HD, and up to 25 Mb/s in 4K. Fibre and the 5G box cover this need with ease. A good 4G box remains comfortable. Only ADSL presents a real risk of slowdown.
Never promise a speed your property cannot deliver. A traveller disappointed by slow WiFi mentions it in their review. Test the real speed on site, at peak time. On the Côte d'Azur, a villa with several travellers needs headroom.
Operator box, 4G/5G box or router: the comparison
Each solution has its own playing field. The table below sums up the costs observed in July 2026. Operator prices change, so check them before subscribing.
| Solution | Typical speed | Indicative monthly cost | Ideal for |
|---|---|---|---|
| Fibre / operator box | 300 Mb/s to 2 Gb/s | €24 to €30/month, no commitment | Property in a fibre area, rented year-round |
| Operator 4G/5G box | 220 Mb/s to 1 Gb/s | €26 to €43/month, no commitment | Property outside a fibre area |
| 4G/5G router + data SIM | 150 Mb/s to 3 Gb/s | One-off purchase + data plan | Owner with several properties |
The no-commitment 5G box is often the smartest choice outside fibre. It sets up in a few minutes, with no technician. For a purely seasonal rental, no commitment lets you cancel out of season.
Which 4G/5G router should you choose?
You pay for the router with a SIM card once, then you only pay for the data. It is the portable solution par excellence. Here are reliable models available in France.
| Model | Type | Indicative price | Ideal profile |
|---|---|---|---|
| TP-Link TL-MR110 | 4G, fixed | Around €42 | Small budget, studio, backup |
| Huawei 4G CPE 5 | 4G+, fixed | Around €90 | Best all-round choice |
| ZTE U30 Pro | 5G, portable | Around €140 | Several properties, portable |
| Netgear Nighthawk M3 | 5G, portable | Around €490 | High end, intensive use |
Choose a SIM card with a large data allowance, or even unlimited. Travellers' streaming uses a lot. An undersized plan gets blocked in the middle of a stay.
Always check the mobile coverage at the property's address before buying a router. A 5G model is useless without a local 5G network. ARCEP's coverage tool provides this information free of charge, address by address.

Managing a WiFi outage remotely
An outage during a stay quickly translates into a bad review. So your ability to act remotely becomes essential. Recent boxes and routers are controlled through a dedicated app.
A simple trick changes everything. Plug the box into a connected socket, also called a smart plug. You can then switch it off and back on from your smartphone. A simple restart resolves most outages. Also set up a guest network, with a password separate from yours.
Equip your property without a second thought
Choosing the offer, installing the equipment and handling outages takes time. Would you like to delegate the management of your property on the Côte d'Azur? Contact the Airbnb Concierge in Nice. We equip and monitor your home.
