I get what you mean 👍 — in Egypt, most Android brands (Xiaomi, Oppo, iPhone, etc.) support Wi-Fi Calling (VoWiFi) normally, but Samsung S series in particular often doesn’t show the option, even though the hardware and software both support it.
Here’s why and what you can try:
---
📌 Why Samsung S series doesn’t show Wi-Fi Calling in Egypt
1. Carrier restrictions – Telecom Egypt (WE), Vodafone, Orange, Etisalat don’t officially whitelist Samsung’s S-series models for VoWiFi. Other brands sometimes bypass this restriction.
2. CSC (Country/Carrier Software Code) – Samsung ships phones with different CSCs. If your phone has an “EGY” CSC, it may have VoWiFi disabled at the firmware level.

✅ Solutions / Workarounds
1. Check if your carrier supports it officially
WE Egypt supports Wi-Fi Calling but mostly for iPhone and some midrange Samsung models.
Vodafone, Orange, Etisalat: very limited Samsung support.
2. Force-enable VoWiFi
Open the dialer and type: *#*#4636#*#* → check if Wi-Fi Calling toggle appears.
Or go to Settings > Connections > Wi-Fi Calling (sometimes hidden).
3. Change CSC (advanced users)
Using tools like SamFW Tool or SamKey, you can switch CSC from EGY to a region where VoWiFi is enabled (e.g., XSG for UAE, ILO for Israel, or INS for India).
After switching CSC, factory reset is usually required. ⚠️ Risk: might void warranty or affect Samsung Pay/OTA updates.
4. Third-party dialer codes
Some users reported success enabling hidden menus with Samsung Band Selection apps from Play Store, but success depends on carrier.

👉 Best practical fix in Egypt
If you really need Wi-Fi calling on a Samsung S series: changing CSC to a region that supports it (like UAE) is currently the only reliable method.
Otherwise, you’ll have to wait until Egyptian carriers whitelist Samsung S officially.

Do you want me to guide you step-by-step on how to safely change CSC for your S series (so VoWiFi works in Egypt), or do you prefer only official carrier-supported solutions?
