SIM Critical® is a product powered by Radio Commz UK Ltd which works in partnership with over 750 Mobile Networks around the world. In the UK we have negotiated priority mast access giving clients ultimate reliability. We have 2 Data Coverage plans available, Europe and World. SIM Critical® mainly comes in 100MB, 250MB, 500MB, 1 GB, 2 GB & 5 GB plans. We also can create our larger client’s custom pools which provide even more crucial savings. An example of SIM Critical®: Let’s say O2 UK went down or was not giving the suitable performance, it would simply switch automatically to the other networks available. Another example: If you arrive in Spain, simply turn the device on, you would automatically be able to connect to all networks in Spain with no extra costs. We also have been advised we have access to the new Emergency Services Network (ESN) masts which are being rolled out by EE on behalf of the Home Office, ESN is due to launch around 2023. So far 19,000 EE Masts have been upgraded and over 600 New Sites are being created. The new mast in Glencoe, Scotland covers 65 square kilometres. Work continues around the Lake District, Scottish Highlands, Wales and around the UK.
