ios how can you tell if phone is in cellphone range and can send a txt
<p>On iphone - how can you tell if you can send a txt - ie if you are in cellphone range
[MFMessageComposeViewController canSendText]   actually seems to mean "Could I send a txt if I was in range"
and</p>

<p>CTTelephonyNetworkInfo *carrierInfo = [[CTTelephonyNetworkInfo alloc] init];<br>
  CTCarrier *carrier = carrierInfo.subscriberCellularProvider;
is not nil even when it is out of range - provided it has connected in past.</p>

<p>is there some other method/function</p>
