I reviewed the TP‑Link M8550 – a go‑anywhere 5G mobile hotspot with VPN and an onboard storage option

The TP-Link 5G mobile router M8550 utilises mobile networks through a paid-for network SIM card, identical to those used in your mobile phone, to connect online. Once done, you can connect to it in exactly the same way as a home or office router, just this one is one that you can take with you wherever you go.
