Dear Support,

I am on the search for the go-to LTE Backup which is NOT a stick on the USB port because 
I want to extend the bandwidth by an external antenna for 4G/4G+ NOT 5G.

I have a MR600 here which is working fine but does not have an option to work in bridge mode or some call it pure mode.

Therefore I have searched the net for an alternative. Now, I found some review of a MR400 which is capabable to do so.

As I am not a friend of Huawei XYZ and other no-names, I have searched hi and low for an alternative, but no luck.

Setup of ER605 is simple:

2 x ISP with fiber 1 GBit. One backs up the other. As there is no meter on the connections and an all-in price, I don't care about which connection is slightly better than the other.

But I need (or I want) is a proper backup by 4G(+) like I have on the MR600 with a data SIM by one of the typical providers in this region.

I have very good results on the MR600 without any doubt, but the ER605 dooes not accept it.

In short: My question is wether I should buy a MR400 to achieve my goal?

Best regards
