The Pakistan Telecommunication Authority (PTA) has advised mobile users across Pakistan to check their phone settings and enable advanced calling features, including Voice over LTE (VoLTE) and Wi-Fi Calling. The advisory, shared through PTA’s official channels on October 15, 2026, aims to improve voice quality, speed up call connections, and keep users connected in areas with weak mobile signals.
What PTA Advised
PTA said users experiencing unclear voice quality or delays when connecting calls over 4G/LTE networks should check whether the 4G/LTE option is enabled on their phones. The authority also advised consumers to make sure both their mobile phones and SIM cards support 4G services, since these features only work on 4G-capable devices and SIMs.
What Is VoLTE and Why It Matters
VoLTE, or Voice over LTE, allows you to make voice calls over a 4G/LTE network instead of falling back to older 2G or 3G networks. When supported by your handset, SIM, and mobile operator, VoLTE delivers clearer voice quality and much faster call connection times. Calls connect almost instantly, and you can continue using 4G data during a call without interruption.
What Is Wi-Fi Calling (VoWiFi)
Wi-Fi Calling, also known as Voice over Wi-Fi (VoWiFi), lets your phone make and receive calls through a Wi-Fi internet connection instead of relying on mobile signals. This is especially useful inside homes, offices, and basements where cellular signals are weak. As long as your phone and operator support it and you are connected to a stable Wi-Fi network, your calls go through the internet with normal call quality.
How to Enable VoLTE and Wi-Fi Calling
Follow these steps on most Android phones and iPhones:
- Check 4G/LTE settings: Go to Settings, then Mobile Network or SIM settings, and make sure the network mode includes 4G/LTE.
- Confirm SIM compatibility: Make sure both your handset and SIM support 4G services. Older SIMs may need to be replaced with a 4G SIM from your operator.
- Enable VoLTE: Look for the VoLTE or 4G Calling option in your phone’s mobile network settings and turn it on.
- Activate Wi-Fi Calling: Find the Wi-Fi Calling option in your call or network settings, enable it, and connect to a stable Wi-Fi network.
- Contact your operator: If these options are missing or do not work, contact Jazz, Zong, Telenor, or Ufone to confirm whether the service is supported on your number and how to activate it.
Important Limitations to Know
PTA noted that switching these features on does not guarantee improved service in every location. Performance depends on three things: whether your device supports the feature, whether your operator has enabled it for your number, and the quality of your connection. Wi-Fi Calling only works when your operator supports it, so check with your network provider if the option does not appear on your phone.
Which Operators Support VoLTE and Wi-Fi Calling
All four major operators in Pakistan — Jazz, Zong, Telenor, and Ufone — offer VoLTE on supported devices, though availability can vary by handset model and region. Wi-Fi Calling support is more limited and depends on both the phone model and the operator. PTA advised consumers to contact their respective mobile operators for details about availability, activation, and use of these services.
FAQs
What did PTA advise about VoLTE and Wi-Fi Calling?
PTA advised users to enable VoLTE, Wi-Fi Calling, and VoWiFi in their phone settings to improve voice quality and stay connected in weak-signal areas.
How do I enable VoLTE on my phone?
Go to your phone’s mobile network settings and turn on the VoLTE or 4G Calling option. Make sure your SIM and handset support 4G.
What is Wi-Fi Calling used for?
Wi-Fi Calling lets you make calls over a Wi-Fi connection in places with weak mobile signals, such as basements and indoor offices.
Does enabling these features cost extra?
VoLTE and Wi-Fi Calling use your regular call minutes and do not carry a separate charge on most operators, but confirm with your operator.
Why can’t I find the Wi-Fi Calling option on my phone?
The option appears only if both your phone model and your operator support it. Contact your operator to check availability for your number.

No, you need a 4G-capable SIM. Visit your operator’s service centre or franchise to get a SIM replacement if yours is old.
Conclusion
PTA’s advisory is a simple but useful reminder: two built-in features on your phone — VoLTE and Wi-Fi Calling — can noticeably improve your call quality at no extra cost. Check that your phone and SIM support 4G, turn both options on, and contact your operator if anything is missing. In a country where indoor coverage can be patchy, these settings make a real difference.
