Samsung Galaxy S10 WiFi calling.

[Oxygen87]

I have placed an order through the O2 website for my new Galaxy S10.

As I'm moving back to O2 from EE, I think I may have to use WiFi calling more as the coverage isn't as good but I'm fed up of various issues I've had while I've been with EE.

The question I want to ask is do I need a device bought directly from O2 to have a WiFi calling device?

I've since seen a better deal through a third party which I know will send me a device with stock Samsung firmware if I cancel the O2 order and get the cheaper deal instead.

Thanks in advance! 👌🏻

Hi @Oxygen87

I believe only phones with O2 firmware installed will allow you access to wifi calling and 4G calling on the O2 network.

So if you purchase a phone through a third party with stock Samsung firmware only you won't be able to use wifi calling on the O2 network.

Hope this helps and welcome to the forum

Tbh I'd ask @Chris_K for confirmation as there are some Samsung devices that work on open firmware.

Good news is the S10 does support Wifi Calling on O2 with open market firmware (eg, stock firmware from the likes of CPW etc).

Thank you for your help guys! The reason I asked is because my Samsung device on EE was from cpw and that has a WiFi calling feature on it but wasn't sure if O2 use their own service or something. 👌🏻

As a matter of interest @Oxygen87  what issues were you having with EE? 

[Oxygen87]

@jonsie Lots of issues regarding billing. My last bill was in excess of £300 being charged for all my calls, texts and data when the calls and texts were supposed to be unlimited and the data allowance hadn't been exceeded. Just a lot of ridiculous things like this. They ported someone else's number in to my account which resulted in them cutting me off and me losing my phone number which I'd had for 15 years! They also billed me £10 for the privilege of them sending me a new SIM card! I also believe that they are selling on customer phone numbers to companies that cold call you. Everyone I know on EE are having this issue with cold callers. I can tell BT own them now... Bring back T-Mobile is what I say! 😂

I can well understand why you changed network then

One thing you need to do though @Oxygen87 

Change your preferences in My O2 as the default setting is to share your number with partners in crime.....

@jonsie thanks! I've checked under 'contact preferences' and all the boxes are unticked. I must have done this when signing up for the contract initially. 😁

I'm loving my new phone! The prism green colour is amazing. 👌🏻
