Regarding vowifi, which telco provide vowifi. So far only tested and be able to use vowifi for: umobile, celcom, hotlink, xox.

How about the other telco?

If in foreign countries, if connected to vowifi for Malaysia simcard, how about the charges for vowifi in foreign countries? Same like using the simcard in local Malaysia?

Could get the sms TAC via vowifi connection if in foreign countries?

Since now handphone got dual simcard, could simcard1 in handphone to use simcard2 internet data to connect as VOWIFI?

Thank you.

Digi and yoodo have vowifi as well.
Yes not supported for now

Unable to answer your other queries. I do notice sometimes my.phone not connected to vowifi even tho got wifi

from my experience, Maxis/Celcom only allows it if you are on malaysian IP address. so going overseas, VoWifi would not appear.

DiGi/UMobile can connect to any wifi and it will work.

interesting to note> DiGi and U Mobile, if you use airplane mode + wifi, you can still receive SMS.

whereas Maxis you only can receive calls. (I presume those that restrict to your own country only you will not get SMS.

for your question, as long as you have Vowifi, you are assumed to be "local". hence local call charges apply.
to ease your doubt, turn off roaming or manually select an overseas carrier that's not supported by your malaysian provider to force it to always have no reception.

on dual sim iPhone, you can use one sim to provide other sim data for wifi calling under this settings. Settings > Mobile Data > Mobile Data > Allow Mobile Data Switching.
then select your data on your local sim, then the simcard you want to have VoWifi would be on secondary.

Using Maxis, oversea cannot use Vowifi.

for best vowifi experience, just Digi or U mobile

im on digi as well..

based on experience, vowifi works everytime im on wifi when overseas.. i made and received call while on vowifi and the standard local rates apply (RM0.20/min when call out to m'sian number, RM0.00/min when received call from m'sian number, etc. depending on what's ur telco charges).. received SMS TAC also fine regardless of vowifi or not

grateful that digi does not restrict vowifi to only works on malaysian IP.. long may it continue.. it saves me some serious ringgit as compare to before.. that i usually does not pick-up call (one that i deem not as important/urgent) if im not on vowifi.. or i call back at a later time when im connected

Wont that be revenue leakages to Digi?

i m using flip4. so far maxis, celcom and digi works. but not XOX black. is there any additional setting i need to do, like APN or something?

Same here. Not getting volte or vowifi.

Is this sim card dependent?

What telco are you referring? Maxis/Hotlink will slow in grants you the said services or you need manually request for it

its always been their policy, unlike maxis and celcom

but digi vowifi was never stable for me, always disconnect locally let alone overseas

umobile has been rock solid in the years ive used it overseas

i even use it with local sim, so can use umobile like im in malaysia when overseas

I'm referring to xox sorry

I got vowifi like 2 months back on xox black. at first few weeks not very stable. now seem stable. it just suddenly connected 1 day. must be changes on their side.

volte was long long time ago like when i subscribed.

Using Digi vowifi at home

Stable and work perfectly in airplane mode, but need set few ports open in router first.

Iinm all telcos in Malaysia now supports WiFi Calling
Digi Celcom Maxis U Mobile Yes Unifi Mobile
Several Yes users (including me on 2023 Oct - Nov) got WiFi Calling already

unifi Mobile and Yes allow overseas IP (CMHK) , Digi allows overseas IP (Chunghwa Telecom / Singtel) , U Mobile allows overseas IP based on whitelisted ASN (e.g. China ISP have their own AS Number based on their province or city, these AS number might not be whitelisted by U Mobile and reject for register on IMS)

What phone support Unifi Mobile VoWiFi?

I use Google Pixel 6, can use unifi mobile VoWiFi
iPhone 13 also can

your pixel 6 is root or non root?

root cuz to use 5G
for VoLTE + VoWiFI , just use Shizuku + Pixel IMS method, it works for non root
