I accept it is not always available - I just wanted to check that we could receive it on this S5 model, which we can. But so far we have not seen it - but I do not always look, and we do not go into cities in the MH.
I've just looked at Kathy's phone to double check.
It is indeed also an SMG900F variant of the Galaxy S5, and it can i deed get data at the "4Gplus" LTE speed here where we are pitched up in Mijas Costa on the Costa del Sol (well, actually it's in the cheap but damn good "New China" Chinese restaurant a couple of hundred yards away from the wild camp parking here!)
As yours is the exact same model then so long as your SIM card contract provides for 4G, then so far as I understand it you'll get LTE wherever you can, and "ordinary " 4G (or less ) when LTE ain't available. Certainly LTE coverage here in Spain is still rare.
