Mobie phone network

Goodday, 

I live in the campo of Competa and we don't have mobile network service. 

We do have wifi but no network for "normal"mobile phone calls. 

I have tried to ask Fobos but they want to sell me a mobile subscription but that's not what I need. I need coverage around ur house. 

Is there a company who can advise us what to do/ maybe we have to install a transmission tower in our garden?

We did install a wifi tower in our garden so we have perfect internet. 

Now all we need is mobile network

Like to hear from anyone

Regards Eva
