I have had nothing but problems with my Note 10 plus. Phone updated in June since then it consistently drops calls.
Check with your carrier, the updates released come through them, could be a tower issue with the carrier or needs to be reprogrammed because some updates change phone settings
Might be a faulty Sim card or not seated properly in the holder or they didn't register the Sim Card correctly on their network... take the Sim card out, power off your phone and put it back in and turn it on
Same here!! I cant even make calls anymore with out it disconnecting from the network.....done so much troubleshooting, sim card etc....sick of this **bleep** already
