#162616 - Not in the US, but... Responding to: ???'s previous message |

But you're in the US, and all the responses so far are from those who aren't That is true, but the 'G' in "GSM" stands for Global - so a good deal of it will be applicable in the US. The one thing that hasn't been mentioned yet is that, as I understand it, GSM is not the only "cellular" in the US - is it? You also have CDMA - don't you? Of course, I know nothing about CDMA! Unlike most carriers in other countries, US provider's want you to get devices from them. They give them away for next to nothing in order to lock you into a multi-year contract. The situation is exactly the same in Europe for "consumer" devices; ie, phones and PCMCIA & USB modems for PC connectivity. I said:
they have absolutely no concept whatsoever of any device that isn't a phone! OK, so I should modify that to "any device that isn't a phone or a PC modem" But it is totally different for the kind of embedded module/modem application that Erik is talking about. I very much suspect that the US is similar? They generally come with an app for sending text messages. That would be a PC app - not much use on an 8051! You can also (usually) download an SDK from the card's manufacturer to control the card yourself. Again, that would be for a PC |
