Response from developer

Thanks for your feedback. We will take this suggestion and update it asap.

Big scam Don’t working with 3G & 4g SIM card

The box very bad quality doesn’t work with 3g and 4g SIM cards and we can’t upgrade the system big scam.

Really! So I have to pay every month?

There are way cheaper options out there that are way cheaper. Vyke will get you a sim for £15 a year. You can receive calls, divert calls to Vyke for travel to overseas to avoid roaming charges. All these for £15 a year. So why should I pay a monthly subscription for mobile sim you can’t really use as a main line. Nothing can replace your main line.
I will advise you guys rethink your options.
