My IT manager looked at my phone and says my SIM card is a very old type that does not support LTE and 4G so it is not the phone that is the problem.
I have had it for a long time, since 3 phones back so it is a couple of years old.
Not sure if that would make a difference, sorry.
The RAIN LTE packages, doesn't matter whom the reseller is, are month-2-month. So, get it, test it and if it doesn't work for you, cancel...? Just make sure about the router, as I know some ISPs only give the B315 for free and some still give the B618 for free, but it has some fine print attached to it. I have 2 packages, one with Afrihost and one with MWEB, both with the B618 router. The Afrihost one I can cancel whenever, without penalties. The MWEB one, if I cancel within 12 months, there is a cancellation fee.
Other than you getting someone with RAIN to come test at your house, there isn't much more info one can give you.
