Got an access code to see your photos?
“service unavailable” or "service access denied" message
Troubleshooting texting your photos code
Contact your mobile carrier and make sure you have "shortcode texting enabled" with your plan.
(It usually is unless you've told them to turn it off)
Make sure you have a cell signal.
Double check that you are texting to the correct number: 90738 and then typing your specific code in the message
