If your Kyivstar mobile internet is unstable or not connecting, the issue might be with incorrect APN (Access Point Name) settings. In this article, we will cover:

  • The different Kyivstar APN options and their differences
  • How to manually configure APN on Android, iPhone, mobile routers, and 4G modems
  • How to improve internet speed and troubleshoot connection issues

1. Differences Between Kyivstar APN: www.kyivstar.net, internet, and ab.kyivstar.net

Kyivstar uses three main APNs, each with a specific purpose:

1. APN: www.kyivstar.net – Default for all users

✅ Automatically set on all smartphones, tablets, modems, and routers.
✅ Suitable for regular mobile internet, social media, messaging, web browsing.
❌ Assigns a dynamic "gray" IP address via NAT, meaning no inbound connections are allowed (remote device management, servers, or VPN hosting will not work).

2. APN: internet – Alternative for modems and routers

✅ Similar to www.kyivstar.net, but commonly used for routers, modems, and IoT devices.
✅ Dynamic IP address via NAT, no inbound connections supported.
❌ Does not provide a public IP, meaning remote access to the device is not possible.

3. APN: ab.kyivstar.net – For business users (public IP)

✅ Provides a public (white) IP address, allowing inbound connections.
✅ Used for VPN servers, IP cameras, remote access, cloud services.
❌ Not available on standard plans – requires a business plan or an additional "Static IP Address" service.

Which APN Should You Choose?

APN Dynamic IP Public IP Inbound Connections Usage
www.kyivstar.net Yes (via NAT) ❌ No ❌ No Standard internet for smartphones, modems, routers
internet Yes (via NAT) ❌ No ❌ No Alternative APN for modems, routers, IoT
ab.kyivstar.net ❌ No ✅ Yes ✅ Yes Remote access, servers, VPN, IP cameras (business plans)

If you need a public IP, contact Kyivstar to activate the "Static IP Address" service.

MNC: 03  
APN Type: default,supl  
APN Protocol: IPv4 or IPv4/IPv6
  3. Save the settings and select this APN.
  4. Restart your phone and test the connection.

If the internet does not work, try changing APN to www.kyivstar.net or ab.kyivstar.net (if you have a business plan).

3. How to Configure Kyivstar APN on iPhone (iOS)

4. How to Configure Kyivstar APN on a 4G Router

  1. Access the router's web interface through a browser (enter 192.168.1.1 or 192.168.8.1).
  2. Log in (default username and password is usually admin/admin).
  3. Navigate to "Network" → "APN".
  4. Create a new APN profile and enter: 
    APN: internet  
Username: (leave blank)
