How It Works.

KeySIM Premium

KeySIM Premium is a highly specialised data SIM which boosts 4G coverage.

KeySIM Premium is unique as it connects to multiple mobile networks whereas a normal SIM can only connect to one to establish its connection to the internet.

By using multiple networks the SIM has a much better chance of being in range of a mobile mast that can establish a 4G connection. Reported figures show that a single network SIM can provide around 66% coverage whereas all four combined can provide 91% - based on these figures KeySIM Premium reduces the likelihood of no connection by over 70%.

Stay connected during an outage

Local Network outages are common as networks upgrade and repair infrastructure, resulting in loss of connection for those affected. Sometimes there are major UK wide outages that have a huge impact on consumers and businesses throughout the country.

KeySIM Premium is a fantastic back up connection for when your primary SIM is effected by an outage as it can switch between networks, if one has an outage it can just switch to another.

Reduce 4G "not spots"

There is nothing more frustrating than being away from your home or the office without mobile WiFi when you really need it.

4G "not spots" are areas where your primary SIM is out of range from a mobile mast and preventing you from connecting to the internet. A single network connection in the UK is up to 3 times more likely to be in a "not spot" than KeySIM Premium which covers an incredible 92% of UK landmass.*

By combining the power of multiple networks KeySIM Premium reduces "not spots" and gets you securely connected when you need it most.

Connects across Europe

KeySIM Premium can be used on multiple networks across Europe.

European roaming data is the same price as UK – there is just a one off fee of £4.95 to enable European roaming which covers you for 30 days.

You can add European roaming by logging to your subscriptions account and setting a roaming schedule.

KeySIM utilises billions of pounds worth of additional infrastructure than normal SIM's. It is designed for when you have no service on your primary SIM and provides reassurance to you and your family or work colleagues that you remain contactable.

1000MB equates to around 1,000,000 WhatsApp messages or 2,000 WhatsApp voice minutes.
