One customer per modem, no resale | | IP rotation | New IP on demand by rotation link or API call, at most once every 30 seconds. You can also set an automatic rotation timer, from every 2 minutes to every 24 hours.

These are the ranges SFR announces. A SIM on SFR normally exits through them, but a port's real exit can differ, for example on a roaming or wholesale SIM: look up the IP your port gives you in any IP database to confirm. | ASN | Holder | What it covers | Source | | --- | --- | --- | --- | | AS15557 | Société Française du Radiotéléphone | SFR ranges; tagged as SFR mobile (208/10) by ipinfo, no registry marker found | [RIPEstat](https://stat.ripe.net/data/network-info/data.json?resource=77.144.0.1) | Checked in public routing data in October 2026.

SFR had about 19.1 million mobile customers in the second quarter of 2026. ANFR counted 31,024 SFR 4G sites in service in metropolitan France on 1 September 2026. On 6 June 2026 Orange, Bouygues Telecom and Free signed a memorandum with Altice France to acquire SFR; Orange says completion could come in the second half of 2027, subject to approvals, so SFR's network and IP ranges may change hands. ANFR lists SFR among the operators with authorised 5G sites on 2100 MHz and 3.5 GHz. RED by SFR is its online brand. ## Which brands use the SFR network? These brands sell mobile plans on SFR's network: RED by SFR, Coriolis, Lebara, Prixtel. Many of them reach the internet through SFR's network, so websites often see SFR addresses for their customers too. A port on SFR can therefore look like a large share of France mobile users, not only SFR-branded ones. ## Is a "SFR proxy" the same as SFR APN or proxy settings? No. If you want the APN or proxy settings for your own SFR phone plan, they come from SFR and are set in your phone's mobile network menu. This page is about something else: renting a proxy server whose traffic leaves through a modem on SFR's network, so that sites see a SFR IP while you work from any connection. ## What is a SFR mobile proxy used for? - **App QA on SFR:** check sign-up, login and payments as a SFR customer sees them. - **Carrier-targeted ads:** confirm which ads and landing pages are served to SFR users. - **Network comparisons:** compare how a page or an API responds on SFR versus the other France networks. - **Brand accounts:** keep a France brand's official accounts on one stable SFR IP. All work follows the [Acceptable Use Policy](https://cellmast.com/acceptable-use/). Blocked: Online banking, government and payment-portal sites, and outgoing email on SMTP ports 25, 465 and 587. ## How much does a SFR mobile proxy cost? SFR ports are in the Europe price zone, as of October 2026. The price is the same for every carrier in the zone, with unlimited data. ### SFR port plans | Plan | Quantity | Price | Price per unit | | --- | --- | --- | --- | | Europe · 1 day | 1 port · 1 day | $4.50 | $4.50/day | | Europe · 7 days | 1 port · 7 days | $18 | $2.57/day | | Europe · 30 days | 1 port · 30 days | $59.25 | $1.98/day | In every plan: One modem and SIM reserved for you · Unlimited data (fair use, no resale) · New IP by link, API or timer · HTTP, HTTPS and SOCKS5 Prices in USD per port.

Send one request through the port to an IP echo service, then look the address up: the ASN is normally one of AS15557. Rotate once and repeat; the new address normally stays inside SFR's ranges. *Exit IP of a port* ```bash curl -x http://PORT_USER:PORT_PASS@gw.cellmast.com:7777 https://api.ipify.org # then look the address up, e.g. https://ipinfo.io/, and compare the ASN ``` ## Other France carriers All France networks and prices: [France mobile proxy](https://cellmast.com/mobile-proxies/france/). - [Bouygues Telecom](https://cellmast.com/mobile-proxies/france/bouygues-telecom/) — France - [Free Mobile](https://cellmast.com/mobile-proxies/france/free-mobile/) — France - [Orange](https://cellmast.com/mobile-proxies/france/orange/) — France - [SFR](https://cellmast.com/mobile-proxies/france/sfr/) — France ## SFR proxy: questions ### What does a SFR proxy cost for 30 days? A dedicated SFR port costs $59.25 for 30 days at CellMast, as of October 2026, or $4.50 for one day. Data is unlimited and rotation is included. The price is the Europe zone price, the same for every carrier in the zone. ### Is a port on SFR 4G or 5G? 4G LTE or 5G, depending on the carrier's coverage where the modem sits. The client area shows the network type of each port before and after you connect, and the network section above sums up where SFR offers 5G. ### Can I get a new SFR IP on demand? Yes. New IP on demand by rotation link or API call, at most once every 30 seconds. You can also set an automatic rotation timer, from every 2 minutes to every 24 hours. Otherwise your port keeps its IP until you rotate it, although the carrier can change it on its own from time to time. Each rotation reconnects your port to the carrier and usually takes 5–15 seconds; the carrier may occasionally hand back the same IP: just rotate again. The carrier assigns the new address from its own pool, normally within SFR's ranges. ### Do I need ID to rent a SFR proxy? No. CellMast does not ask for ID, a selfie or documents to open an account or buy a plan, and you never hold the SIM. Login with an account number; email is optional. You pay in BTC, USDT, USDC, ETH, SOL, LTC from a $25 top-up. **Rent a port on SFR** SFR 4G/5G modem from $4.50 per day, unlimited data, rotation included. Pay in crypto.
