The m obile phone signal booster for vehicles seemed to get round the need for an additional SIM and for about the same initial cost. Also, I was somewhat confused about what kinds of EE SIM cards I could use. That's what put me off as it seems like an ongoing expense when we already pay a hefty monthly fee for unlimited data on the phones. I did look at motorhome wifi systems (rooftop antenna plus router) - for example the Maxview Roam - but these seem to require an additional SIM card. We tour a lot in Scotland and we have found that there are quite a few rural areas where a pay-monthly EE plan can pick up a signal but where a MVNO plan will have no signal - I presume these are areas where the masts broadcast on the extended-range 800MHz frequency. We go online both on our iPhones but we also tether our laptops to our phones. Cel-Fi GO Smart Signal Booster for Telstra 3G or 4G - Caravan & Marine Kit SKU: CELFI-GO-MAM-KIT 979. We hardly make any phone calls but we do both use mobile data to get email, browse the web, stream movies, use WhatsApp, do online shopping, use satnav etc. My husband and I both have pay-monthly SIM-only plans, one with unlimited data. That's some useful additional information, thanks.
