How hard is it to send a text from a PC, if you don't know, didn't ask,
the cellular carrier for the cell phone?


A couple days ago I bought some elastic online, and they offer to find
it in the store and bring it out to the car.

They say when the order is ready they will text me the store's phone
number.

The webpage first said order was in process and then pending pickup. 90
minutes later I went there and they brought it out, as they said they
would.

But the text never came.

I would have expected it the text to be sent automatically when the
order status is changed to pending pickup. But that assumes a PC can
send a text** and I thought they would have to know the cellular carrier
prefix to do that. That seems like a big hole that should be plugged.




**Well, it can using MyPhoneExplorer, but that doesn't seem widely used.
What alternative might be built into a PC program?

If you know the telephone number all you have to do is enter it into the
box on this site, and it will give you the text address.

This site then gives you the domain for that telephone number.

ie

The catch is that the person responding to your text must reply to the
text, as it comes to you as an email. If they try to create a new text,
it may not work unless they send it to your email address.

In the case with the store, I assume that tried to text to your phone
and it will not come to your computer because it is to the your
telephone number and your domain not to your email address.
