Hey guys,

I need some help that I'm just a little unsure about.

For our business phone, we get a corporate plan. Unfortunately this is provided to us via Vodafone's mobile network, so we have a rather unreliable Huawei cordless phone set, with the base station containing a sim card. Ideally would switch to a VOIP line but this is not an option, thus am stuck with the sim card plan.

I am looking at replacing it with something like this

so that we can go back to our old phones that at least worked throughout the building. 

I am aware that Vodafone is intending to close the 2g Voice network, so would I be correct in saying that because it is GSM900, that is 2g?

Many thanks :)
