I've recently switch to Virgin mobile and kept my old number. This weekend I have tried to text 4 friends. 2 of the texts were delivered and 2 not. I texted the message to my husband he successfully sent it to the 2 friends so we know their phones are working. I've spoken to Apple as I have an iPhone 5s and they say its a problem with Virgin. Any ideas how to fix this?
I don't know which network my friends are with but their numbers are not similar. They don't have iPhones.
