phone only sending texts to other iphones

[desi11]

since monday my phone has been sending texts to other Iphones and it only works if it says Extended it won't do anything if it has 3g service, I live in south texas, I'm not sure if it's my phone or if a tower might be down in my area,also I can only make/receive calls when it says extended if i have 3g and make a call the other person can't hear me, I just got my phone in about November so I hope it's just a problem with the network,has anyone had this problem?

Yes, my daughter is having the same issue.  We are trying to reset all settings to see if that helps
