Cannot change voicemail speed dial number (Nokia 5 stock Oreo firmware)

[Anonymous]

Hi

I bought this phone last week (from CPW) as SIM free because I wanted to ensure that I got the security patches as they came out as a lot of UK operators sit on patches for months while they test them.

Took delivery of the phone, charged it, booted and connected to my home wi-fi and it installed the Oreo update and then the March security patch, then I shut it down and put the SIM in.

Great phone but one little annoyance.

I've been on giffgaff but am porting back onto O2 PAYG tomorrow just because it's cheaper for my usage pattern.

On both SIMs I've had an issue where the voicemail speed dial sticks on 905 (which I know if the short code for Tesco Mobile), I've tried to change it to 901 through the settings but it indicates it cannot, tried a factory reset but it won't change.

I contacted HMD through their support app and just like the error message they referred me to my operator, I explained that as it's SIM free they may not be interested in assisting me but this didn't sway them.

Booting without a SIM gives no menu options under Voicemail so setting it this way is a non starter, anyone else seen this and fixed it?

It's a known software bug in the firmware.
Customers have to dial 901 manually until Nokia roll out a fix.
