I have a Samsung Galaxy Note 8. It has all available updates installed.
The person I'm trying to text also has Verizon and is on an iPhone. I can call this contact without issue.
I've done the following already:
- Deleted the message thread from my texting application.
- Deleted the contact.
- Rebooted the phone.
- Readded the contact without the +1 prefix
- Messaged the contact again, still getting "Error 5: Other Network Problem" when trying to text this contact.
- I've even tried other text messaging apps to no avail.
- I can text anyone else without any issue from any other text messaging app.
