4G LTE Mall  Huawei E5180 4G WiFi Cube Replacement?

I'm still using the above router since 2016.  I love that I can use it anywhere in the world by just buying a local SIM card and plugging it to the wall.  But it's now outdated security-wise.  

Can anyone tell me the brand/model of a similar much newer router?  I'm looking for one with a SIM card slot and power cord.  I've seen a few that have batteries, but I prefer to plug it to electricity (if it has both, then OK).

Thank you.

Update:

And, is it safer to use other brands other than Huawei?
