Hi, I'm having problems trying to successfully send messages to mobile phones.

The numbers I'm trying to send to are Jamaican and US numbers.

1876123456 [the '123456' is to hide the actual number I'm trying to send to]
but, anyway. This is is the format I use and I still get status: RE

I KNOW these numbers I'm trying to send are in service! so it must be the number format

I'm wasting credits n it's making me frustrated! I didn't come here to waste my money!

I've tried to reach out to customer service through email and they seem to be avoiding this question
