simultaneous texts

I was on a train many years ago and texted a friend who I had been out of touch with for a month or so, as he was on a long trip. I asked when he was coming back, and I got a reply back maybe 10 or so min later. He completely ignored my question though and was asking me something totally unconnected in return. I replied but heard nothing back. Later that day he emailed me with his question again, saying: "not sure my text made it. I can't receive any right now. no reception...". When I asked whether he had received mine and was texting in return, his reply was: "I am currently still in the states, and will probably get your text, once I have reception again." I still have the email exchange. It seems it was sheer random coincidence that we thought of each other and wrote at the same time. Or a telepathic connection! Which is how I think of it. This happens to me on multiple occasions (sometimes thinking of a person and immediately getting a phone-call or text from them), but often with people I see on a more regular basis, so it is more likely that we simply think of each other at the same time for no deeper reason than a random coincidence.
