Major UK networks backtrack on promise not to reintroduce EU roaming charges

Despite assertions to the contrary, UK networks are reintroducing high roaming charges following the UK’s departure from the EU. So if you’re planning on using your phone abroad it is important to make sure you’re not caught out by “Bill Shock” by checking with your carrier before you go. 

Better still, why not join ONSIM where we will continue to offer our customers roaming in the UK 🇬🇧, EU 🇪🇺 and USA 🇺🇸 at no extra cost!



It’s finally arrived! Probably our most requested feature has been released today with the introduction of the long awaited eSIM. We’re thrilled to be able to position this alongside our regular physical format SIM’s as an easier way to deploy our business network solution to eSIM compatible devices.


BT ISDN Switch Off 2025

As the impending switch-off looms ever closer we wanted to offer a gentle reminder to any customers still considering or* currently using ISDN PBX phone systems that BT confirmed that the ISDN network will be switched off by 2025 forcing customers of the UK’s roughly 3 million ISDN lines to migrate to IP services whether or not they are available, stable or suitable.
