If you are hapoy great, if not, consider the following:
-If you can't call out, try rebooting your phone. This helps 90% of the time for me.
-You can also try toggling airplane mode on, then off.
-You can always take out and reinsert your SIM card.
-If you wonder what your download speeds are, be sure to use the Verizon suggested site:
-If you have an issue, you can start a chat session with Visible tech support.
-Lastly, if you have a 5G phone, sme people are finding 4G service is still faster. Run a speed test under both scenarios.
If my advice helped you, "kudos" would be appreciated as well as accepting my solution.
