Hello I have a samsung a20 and am having trouble sending texts to one of my contacts. I can receive calls and texts from this person and can make calls to this person but when I try sending a text to this number from my residence it is not received on his end but looks like it has been sent on my end. I have tried sending texts to this person when I am closeby and the texts are received. Anybody have any ideas of what the problem could be.? Thanks
