4G/5G Mobile WiFi Dongle or Router (Cumberland street EH3)

Hi everyone, we’ve just moved to the area and are looking for a 4G or 5G mobile WiFi dongle/router — the kind where you can insert a SIM card to use the internet. Thought I’d check here first before exploring fibre options. If you have one lying around that’s not in use, we’d really appreciate it. Thanks so much!
