  • Those are valid observations, but the different technologies all terminated to the POTS network, so phone calls across networks always worked. But it was just considerably more expensive to make phone calls on mobile than land lines where you could get flat-rate unlimited calling (local, not long distance, getting a cell phone then could potentially be cheaper for long distance). It was the early 00s when flat-rate unlimited plans were becoming common in the US, and that’s when people started ditching their land lines.

    AT&T was notable for being the first one (of the Big 3) here using internationally compatible GSM in the 90s. But it actually wasn’t until LTE that Verizon stopped using CDMA for data (but they still used it for voice) in 2010 when we finally started seeing things trend towards adopting a common standard in the Big 3 national carriers. Sprint went with Wi-MAX instead of LTE for data at that time, and having to retool to LTE was one of the financial straws that broke their back.


  • It’s like how the US got so far ahead with reliable universal twisted-pair phone lines, it took a lot longer here for people to really start having just a mobile phone compared to countries that were able to side-step their inadequate landline infrastructure with mobile phone services. WhatsApp largely gained prominence in countries that had much more cost effective data plans than SMS texting, making WhatsApp cheaper than SMS along with being available at all on Android (vs iMessage). In the US we had unlimited SMS messages included in plans before anything approaching that for data. So in the US SMS was already quite well entrenched in social circles by the time iMessage came out. And Apple knew that people wouldn’t be so loyal to iMessage if they couldn’t message with whatever non-trivial percentage of the social circle didn’t have an iPhone so it inlucded SMS-fallback. There’s plenty of WhatsApp and Signal users in the US at this point. But nobody cares enough to try and get everyone to switch to one platform that is available everywhere and doesn’t have SMS fallback, so SMS is still the glue that holds all the messaging together in the US.

    edit: I think I can safely say it’s going to take the big 3 carriers in the US all agreeing to drop SMS (which pretty much will probably take the GSM standards body dropping SMS) for the US to truly move off of it.
