Due to SMARTY dropping 3G in my area I've just replaced my Huawei B311 4G Router with a Tenda Wi-Fi 4G VoLTE Router (Model 4G06v1.1). It works just fine bar for one thing. When trying to login to Amazon or a bank the OTP message they send me via text (SMS) arrives as rubbish! The SMS from Amazon is just a string of @s. Texts sent from friends phones are fine.
Anyone any idea what's going on? tia, fuzzy.
