While you may see a carrier update pop up randomly on your i Phone, or a request to install one during a general i OS update, you can also manually check for these carrier updates on your own at any time.Carrier updates are usually quick and fairly inconsequential, though it’s still good policy to backup your i Phone before attempting to install one.So toggling the "Enable LTE" function to "Data Only" in the settings panel seemed to temporarily solve the issue, according to .There is also the possibility that the issue stems from a fundamental flaw with how the i Phone 7 using i OS 10 interacts with any CDMA-based network, which includes those of Verizon, Sprint, US Cellular and numerous other international carriers.If you see something capitalized, then capitalize it in your settings.If you see a comma, use a comma, if there are no spaces between the comma and other words, then don't make spaces between them and the words in your settings.Some users of different networks have reported similar service problems, so this may have extended well beyond Verizon's customer base.Whatever the true problem and its source, Apple has issued an official fix.

From time to time, your cellular network provider or Apple may issue a carrier settings update to an i Phone or cellular i Pad device.
The updates are usually very small and make adjustments or improvements to carrier specific settings pertaining to the cell network, data, personal hotspot, voicemail, text messaging, or making calls.
If you still find they don't work, try rebooting your phone.
If you still don't have success, leave a comment so the issue can be looked into.
