If you’re using a mobile phone in New Zealand, it’s essential to know which frequency bands your phone supports. These bands determine the quality and coverage of your network connection. Checking your phone’s frequency bands helps ensure you get the best service for calls, data, and messaging.

Why Frequency Bands Matter

Mobile phones connect to networks through specific frequency bands. Different networks use various bands for 2G, 3G, 4G, and 5G services. If your phone doesn’t support the correct bands, you may face poor signal quality or slower internet speeds. By knowing which bands your phone supports, you can select the best mobile provider and plan, especially if you’re switching networks.
