How good is the signal strength where this is happening? If you have a good signal strength and have gone through the user troubleshooting, the last thing I would try would be to remove the SIM card, wipe with a clean, dry cloth and then reinsert them. If this doesn't help, then contact the carrier as this could be something with your account. It is very unusual for two devices to display the same behavior together like that.
