As we all expect at this time every year, the new iPhones have arrived and again we get two new phones in 2015, the iPhone 6S and iPhone 6S Plus.
Both of the models features significant upgrades like 3D Touch, 12MP iSight camera, 4K video recording, faster CPU and GPU performance. The phones were launched with the 16GB, 64GB, and 128GB storage options but the 16GB and 64GB were discontinued and replaced by the 32GB option since 2016. You must be excited about the launch and want to get hands on the phone as soon as possible. However, you should be careful because your new iPhone might not be compatible with your carrier.
The iPhone 6S and 6S Plus come in 8 models, including A1633, A1634, A1687, A1688, A1699, A1700, A1690, and A1691, and they have different cellular connectivity. Fortunately, the number of model numbers is the same as iPhone 6 last year and Apple also covers 3 more LTE bands (23 as compared to 20 bands on iPhone 6). If you are on T-Mobile, you will see a boost in LTE signal, especially when you are inside buildings, because all new models include support for LTE band 12 (700MHz spectrum). AT&T customers will also notice a better experience as some models support the new LTE band 30. The new generation also features LTE-Advanced (LTE-A) which supports download speed of 300Mbps and Voice-over-LTE (VoLTE).
Now, let’s take a look at the different model numbers.

Looking for which iPhone 6s Plus will work in western Canada? I’d like a 128 GB phone, and one with the fingerprint scanning/passcode if possible. Knowing which ones will work in Canada is necessary, as well as when I travel to the U.S. Perhaps knowing which one’s ‘won’t’ work should be known too?
Thanks in advance.

My granddaughter was given a model A1634 IPHONE 6. I was told that it was a 6s+. Now I have no ideas about this phone but would like to find out whether or not it has any of the settings – 16GB, 64 GB, OR 128GB, and how can I tell? The person who gave it to her is no longer around so she has no idea or information regarding this phone. How can I find out how to unlock or activate this phone for her myself. Any help would be greatly appreciated as I live on a small pension and expensive phones aren’t cheap to find someone who could help me. Thank you if you can.
