Trigger notify problem

I am using a Wemos D1 to monitor the water level in a water tank with a float switch and it works as intended I can watch the data when triggered and have it set to send a notification to two phone numbers when triggered and it sends to the second phone number I added but not the first

what is the format you have added your contact number? is the country code correct?

I entered area code and phone number

can you private message me your email_id used to login into cayenne.

Adding a 1 to the phone number fixed the problem
Thank you
