VoLTE and 3G switch off - Oppo4

[RichardE_567944]

Hi all, I have an Oppo Reno4 Z 5G. (CPH2065).

No problem until 3G was recently switched off at my home address. Now I cannot make or receive phone calls on Smarty. My phone does not show any option in settings to select VoLTE, or LTE. However, I can select 2G, 3G, 4G, 5G (auto).

My SIM card works fine from this location if I use a different device (Samsung Galaxy).

My phone works fine if I use a Three SIM card.

Oppo suggest this is a network provider configuration problem. Smarty tech suggest this is an Oppo problem. 

Any ideas or known solutions? Thanks...

Hi @RichardE_567944 👋

Unfortunately your handset is on the list of those 'unsupported' by SMARTY.

I have also found this to check if the VoLTE option is available on your handset (If not, 'Google' is your friend to see how you may be able to enable the option)...

Have you looked at iD Mobile? Your handset is on their 'Approved' list and also uses the 'Three' network (just like SMARTY) and have comparible packages (please do the research to see if it fulfills your needs as some things are different i.e. MMS messages are chargeable with iD but are free with SMARTY)....

Hope this helps to point you in the right direction! x

Thanks Decembersangel, 

my handset, a Reno4, isn’t on the Smarty list (that’s a Reno2), and all the tech people agree it should be working..!

I think I’ve actually worn Google out, and it’s no longer my friend 🤣

Having very long chats with techies from both Smarty and Oppo - the Oppo tech suspected there was a problem with the Smarty 4G signal . Smarty and Three are now both showing a problem with services in my postcode, and assure me that my phone will work again once they’ve sorted it.

Thanks for your replies…

My area in Norfolk are in the process of switching to 4G and this past week I can’t send or receive calls. NR29 area. Wonder if it’s just a case of wait and see? I’m loathe to get in touch with customer support as I find it all very confusing.
