TalkTalk network coverage

TalkTalk network coverage

As TalkTalk uses the Sunrise network, TalkTalk customers can rely on a very good infrastructure. Accordingly, the network coverage for 4G/LTE is over 95%. However, you can find out whether the network is really that good in everyday use by asking family members, friends or colleagues. You can also use the Sunrise network coverage map to check availability in your location.

How good is TalkTalk's network?

Thanks to the Sunrise network, TalkTalk customers can surf in one of the best networks in German-speaking countries. Sunrise was the only mobile phone provider to receive the top rating "outstanding" four times in a row in connect's internationally recognised quality benchmark test. However, this result cannot be transferred 1:1 to TalkTalk. 

TalkTalk 5G network coverage

Talk Talk has 5G network coverage of over 80% thanks to the Sunrise network. Network operator Sunrise has been investing in the expansion of the 5G network since 2018. TalkTalk customers have been able to access the 5G network since 2021.
