How do I know if my phone supports 4G Calling? - To check if your phone can use 4G Calling (also called VoLTE), you can look at your phone’s settings or check with your mobile carrier. If your phone supports it, you will enjoy clearer voice calls when using the booster. 4. What area will the booster cover? - This signal booster is great for medium-sized areas, boosting signals in places up to 250 square meters. It's perfect for homes, cafes, restaurants, and other spaces where good phone and internet connection is important. 5. What should I do if I have no signal outside? - Signal boosters can only make existing signals stronger; they cannot create signals. If there's no signal outside, the booster will not work. You might need to find a better location for your outside antenna or check with a provider for service in your area. 6. How can I check which frequency band my device uses? - You can check your frequency band by dialing \*3001#12345# on your iPhone and selecting 'Serving Cell Info'.
