There really is something wrong with my phone

Or is there something wrong with Smart? Or Globe? Or both?

Why do people I send text messages to receive them late? Like fifteen minutes late, or even more? Is it with the signal interferences? In this modernized world, wherein busy lives are influenced by long-distance communication, nobody can't afford to waste precious time in between SMSes. What if your life depended on one text message?? Say you were kidnapped, and you wanted to message an SOS to someone, and you desperately needed help ASAP because the kidnapper would be transferring you elsewhere, you couldn't afford to lose time, right? This one's extreme (but still probable). Anyhow, if you wanted to meet someone, and say you were waiting already for almost an hour, as the person you were waiting for received the message about the meeting place an hour late, it's a grrr, right? I've already tested the networks on their punctualities, like sending an SMS to a nearby friend, and asking him if he received it already seconds after sending. And results say he received it on time. So what does it differ when it comes to longer distances? Yeah, sure: waves do travel faster for shorter distances, but the radios already proved that it's just a matter of seconds.

The point is, why can't they just send it on time? They can do it real-time when it comes to calls, they can also do it in texts.
