Changing from iPhone to Android, others have to reset iMessages?

[PACWEST]

I had an iPhone, changed to an Android. Those friends with iPhones, their texts weren't coming through until the turned iMessages off, sent me a text, it worked. Then they could turn iMessages back on and was still able to send me texts. I would think using iMessages between two iPhones wouldn't some how lock up how SMS's are routed? I wonder if it's a network thing?

I have had success just turning I message off before my SIM comes out and I have had no issues with other I message users.. except for the question "why????"

I was careful though not to use my email address as primary.. only my number as I don't want to use I message on my ipad .. just would get too confusing to keep track of methinks.

Yep! It's a pain. I switch between Iphone4 and HTC inspire every other week. Any Imessage communication I have and is responded to when my sim is in the inspire, does not get delivered to the inspire, but stored on the clouid. When I put the sim back in the iphone, they start to come in. What a pain! What I have done, is ask people to send me a new txt, ratrher than respond to a threasd we already have going. Or, I can just send a txt from the inspire to any of them. In that case, if they resply, I will get it on the inspire.

You wonder why? That's really easy. If you remove the SIM from your iPhone, Apple's iMessage servers don't know whether you moved the SIM into a different (non-iOS) device, or whether your iPhone is just turned off (or out of range) for some reason. They have to assume the latter, so any messages are stored in the cloud and will be delivered if the SIM returns to an iOS device. Unless the sender has the "Send As SMS" option activated, in which case the message will be converted to SMS immediately (and delivered to whatever device currently holds your SIM) if your iOS device can't be reached. Turning iMessaging off before removing the SIM card accomplishes the same thing. It lets any sender know that your address is no longer capable of receiving iMessages, so they won't be sent in the first place. But if you just remove the SIM without warning, the messages will be stored in the cloud as previously described. Makes perfect sense if you think about it.

You would have to disable it on your iPhone or after a while the message realizes it can't send because the other person isn't available so it will send as a regular SMS.
