My Huawei B311 (4G) router has suddenly started receiving phone calls!

[fuzzy]

When SMARTY dropped 3G in my area my Huawei B311 router stopped receiving phone calls (and I bought a Tenda N300, which receives OTPs as a string of @s). This morning it is receiving calls. The light on the router turns blue which, AIUI, means it's dropped to 3G. What's going on? Anyone any idea?

Anyway, I hope it stays this way.

fuzzy.

PS. Anyone want to buy a Tenda N300 router, going cheap?

Interesting to hear, but if it is indeed dropping down to 3G (which I think it will be as I don't think the device supports VoLTE), I wouldn't expect it to last long unfortunately, as I believe it is still Three's plan to switch off all of their 3G coverage sooner or later. Maybe they've temporarily switched 3G back on in that area due to coverage issues from their 4G, or maybe it's just a mistake.

Let us know if it lasts!
