Is 3G network always available when 4G network is?



  • I'm going to buy an Android phone which has unfortunately blocked 4G calls by the operator. Only 3G calling will be possible. I think it's enough for voice, but:

    Since I travel a lot, is the 3G network available everywhere when 4G is? Or is it completely different technology so I might end up in the places where only 4G signals are available, but no 3G?



  • I had to discard fully functional smartphone because we have no more 3G in germany. This concerned UMTS mobile data only, GSM phone calls still possible.
    Nevertheless UMTS is independent from LTE so the answer is NO
