2013 article, but, it explains why World Phone style devices (for us routers) became difficult after a good long run with Quad Band 2G – 3G stuff. BUT THINGS ARE IMPROVING !!!!
“Doesn’t it bother you that Apple sells its LTE devices like the iPhone 5 and latest iPads in a bunch of variants, depending on your carrier and geographical location? For example, the iPhone comes in two GSM models and one CDMA version. Blame it on the limitations with existing wireless chipsets, not Apple. Long-Term Evolution (LTE) is a fantastic technology, but it’s also highly fragmented.
And with nearly fifty different cellular bands in use globally worldwide, no wonder LTE is a bag of hurt, one that has introduced fragmentation unlike any other cellular radio technology before it.”
* Anyway newer Qualcomm chips – even newer than described in this article – have come out that supposedly solve this problem. The newer ones are firmware changeable to change what carrier and what frequency bands they support. There is even a new Sierra Wireless Card that has many of the firmware’s already onboard – and easy switching? So it’s easier to change where it will work. Hopefully router manufacturers jump on this … as well as the multiple-Voice capabilities up to VoLTE in 4G LTE … so that another SUPER world capable voice and data router can be made.
(And, BTW, you can blame it also on Apple because they go cheap the first time around when a tech change becomes available they are too cautious and cheap and screw one model generation because of it. This is what happened in iPhone 5. iPhone 6 got the LTE-A baseband. I’m not sure if it got the World capability or not, maybe someone can comment if they can easily change the bands or carrier tech in iPhone 6? The MDM9615 is in there … but is the baseband firmware easy to change? Likely not. Unlocking based band supposedly can even be FREE and EASY? http://iphonegeeks.us/ Use at your own risk. There were several Chinese baseband unlock things wanting money to UNROCK ur PHONE. You give money you go home now!)
