TL;DR
- Proximus is one of the leading mobile networks in Belgium, and for a company operating only in Belgium, it is a perfectly good domestic choice.
- The hassle starts at the border. A national carrier covers one country. An international company on Proximus ends up adding a second carrier in the next country, then a third — each with its own contract, invoice, portal, support queue, and pricing logic.
- Telgea replaces that accumulation: local plans on leading networks, unified under one agreement, one invoice, and one platform — its own MVNO in 15 countries today, expanding to 26 by the end of 2026 and 50 in 2027, with new countries stood up in roughly four weeks.
Where Proximus Is Strong
Proximus runs excellent Belgian infrastructure and serves domestic businesses well. Nothing in this comparison argues otherwise — if your entire workforce sits in Belgium and always will, a domestic carrier is a reasonable answer.
Where a National Carrier Becomes a Hassle
- Every new country is a new vendor. Hiring in a second market means a second carrier relationship: procurement, contract, portal, billing, and support — multiplied per country.
- Roaming was priced for visits, not for teams. Employees who live across borders on a single national plan generate bill shock or workarounds like personal SIMs and travel eSIMs on expense reports.
- No single view. IT and Finance lose central visibility the moment plan number two exists at carrier number two.
- Onboarding drags. Getting a new hire in another country connected through a domestic carrier's processes takes days or weeks, not minutes.

The Part Most Companies Miss
Switching to Telgea doesn't mean giving up domestic network quality: Telgea plans ride on leading local networks in each market. Employees keep local numbers and local-grade coverage — the company just stops collecting carriers.
Bottom Line
Keep a national carrier if your company is national. If it's international — or about to be — Telgea gives every employee a local plan under one agreement, one invoice, and one modern platform, from a team that was named Best B2B Mobile Operator at the MVNO Nation Global Awards 2025.
