Anyone who has the Google voice app and uses it for texting may wounder about the delay. Do you get text messages as quickly as if they were sent to your real cell number and not your Google voice app? IF you have explored the Google Voice application the minimum refresh interval is 5 minutes. So one would assume you could be waiting up to five minutes fofr a text to get to you sent by a friend but this is not tru as proved by some tests me and joegrind (from the forum).
Our first test was a base test and he sent a text from his cell phone to my normal cell number (not my Google Voice number) and I received the text with in seconds after him sending it.
Next I had him send a text message to my Google Voice number. But right before I ha him send it i went into my gv app and did a manual refresh to make sure it would start its 5 min refresh interval right then to get accurate results to see if GV actually "pushed" the sms to my app. the message was sent at 8:35pm and I did not receive it until 8:40pm proving that gv does not "push" sms messages to its app.
Next we decided to test out a theory some have that if in your Google Voice settings you have the setting checked off in which it will send text messages directly to your phone (not just to gv app but to your built in text messenger) that you would get texts instantly. Upon testing this it proved true at first. If you have the setting checked to send messages to your cell then they come up in GV app instantly to. We tested this a few more time and got the same results but then joe grind came up with this theory, "I think as the gvoice dialer recognises the 406 numbers...it gets faster"
So I then we decided to go back and test this, by going back into my settings and turning off the send text to cell phone option. Upon doing this, in the next two tests i still got the text messages just about instantly.
What our results seem to prove is that one you have received at least one text from a number Google must first assign a 406 number behind the scenes to it (even if you don't uses the 406 #) then after the incoming number is recognized it speeds up delivery of the sms to your gv app.
last note is that this was only tested with the android gv app on the Motorola Droid. We have not tested the blackberry GV app.
What do you all think?
