Solved! Go to Solution.
You are not the only one, i have the same issue, i got new 5G sim card from Verizon and tried 100 solution to fix it, but failed, sounds like Samsung note 20 does not support Verizon 5G nationwide. and i just ordered IPHONE 12 PRO MAX, time to change the phone, it support all the 5G. I have no idea why Samsung did this to me, and i paid 1 month for 5G and still stuck with my stupid 4G! waste my money!
