Roam at Home

---

Domestic mobile networks within the same country don’t allow local competitors to roam on their infrastructure because they operate in a highly competitive, commercially protected environment. Each network owns exclusive rights to a portion of the licensed spectrum, and there’s no regulatory obligation to share it with rivals. Letting local competitors use their network would dilute their competitive edge, reduce customer loyalty, and risk overloading infrastructure built specifically for their own users.

Yet paradoxically, these same networks are required (often by international agreements) to allow foreign SIMs to roam on their networks. This is part of a long-standing system to ensure travellers can stay connected abroad. Yet to the average domestic user, this makes little sense. Why can someone visiting from another country access multiple networks, while a local resident is stuck with just one?... Even if there is a network outage, the signal is weak or there is no coverage in certain areas?

The result is a strange situation: if you want the best mobile coverage in your own country, you're often better off using a roaming or international solution like trvllr. By leveraging roaming agreements across all domestic networks, it ensures you always get the strongest signal, without being locked into a single provider’s limitations.
