strung Posted May 11, 2012 Share Posted May 11, 2012 When I text on Sprint (iPhone) it takes about 5 seconds to send. When the phone is on Extended network, it sends almost instantaneously. What's up with that? /edit This was regular Text message not imessage, sending to a phone on AT&T. And I also tried sending to 311 the "usage" command and it send and replied back instantly.

Deval Posted May 11, 2012 Share Posted May 11, 2012 Interesting, usually Extended means you're roaming (I think, don't have an iPhone myself). I've never heard of that, normally roaming is slower. Quote Link to comment Share on other sites More sharing options...
bkco14 Posted May 11, 2012 Share Posted May 11, 2012 (edited) When I text on Sprint (iPhone) it takes about 5 seconds to send. When the phone is on Extended network, it sends almost instantaneously. What's up with that? Mine works the same way. Since Sprint's 3g speed in my area tops out at 30kbps, roaming is almost 5-7 times faster. That may explain your situation. Have you done a speed test of Sprint's speed in your area? (this is for iMessage as iMessage uses the data network) Edited May 11, 2012 by bkco14 Quote Link to comment Share on other sites More sharing options...
cletus Posted May 11, 2012 Share Posted May 11, 2012 I've notice this is the case only when sending to friends who use Verizon (as the roaming is on verizon) Quote Link to comment Share on other sites More sharing options...

irev210 Posted May 11, 2012 Share Posted May 11, 2012 When you are on extended, you are already on 1x (which is what txt msg goes over). It's faster because it doesn't have to switch from EVDO to 1x to send the text. 1 Quote Link to comment Share on other sites More sharing options...

It's faster because it doesn't have to switch from EVDO to 1x to send the text. Hmm. But if I turn off cellular data and 3G, it's still the same speed (about 4 to 5 seconds). Not sure if this puts it into 1x mode though. Quote Link to comment Share on other sites More sharing options...

Hrm, I am not sure why that would be. Interesting - I am not sure. Quote Link to comment Share on other sites More sharing options...

Nope, from an RF standpoint, that does not shut off EV-DO. Your handset continues to monitor an EV-DO carrier; your settings just prevent any data usage. I have verified this by watching the field test debug screen. AJ 2 Quote Link to comment Share on other sites More sharing options...
Sandman Posted May 11, 2012 Share Posted May 11, 2012 I get the same behavior too at the house and I am on 1xRTT. I rarely get EVDO revision A or 0 at the house. Once I am roaming and on Cricket, the texts are sent instantly almost. Also for some reason on my EVO 3D, while roaming, I can't get new texts. I have to switch back to Sprint to get the new texts. When roaming, it will keep sending me the same text over and over again. This only happens on my phone and this is the 3rd EVO 3D Sprint have given me with the same behavior. My wife has an iPhone 4s and doesn't get this behavior with her phone. This also happens while in other parts of the city I might drive to.

zmccaa Posted May 12, 2012 Share Posted May 12, 2012 I have found that on my iPhone 4S, I have the 51087 PRL that allows Verizon 3G roaming (at least in my area, Avon, NY) because on my Evo Shift and Epic 4G I have never seen 3G roaming, but with my iPhone when it switches to Extended, the 3G speeds to from .6-.7 (Sprint) to 1.25 (VZW) and when I call *2 it gives me an VZW error message.....weird I'm not on the 60687 PRL...I have an Evo Shift activated and I can say that it always roams at 1x and my iPhone roams at 3G Quote Link to comment Share on other sites More sharing options...

One thing I noticed with my iPhone I had on at&t is that it took 4-5 seconds to send a text message, and that was long before iMessage existed.

Abyss19707 Posted May 12, 2012 Share Posted May 12, 2012 I have Sprint and roam offen in my house. It usually takes me 4-5 seconds max to send a text on Sprint's network but roaming forget about texting. My messages almost never get sent if I am roaming. If it were not for iMessage then I would not be able tot text my friends and family (most have iPhones) Quote Link to comment Share on other sites More sharing options...

zmccaa Posted June 12, 2012 Share Posted June 12, 2012 How did you get that PRL on your phone? That is the PRL that the iPhone uses from Sprint. I have not loaded it my self but got it from ##UPDATE# because the 31001 (I think) came with the iPhone and gave me problems. I have never seen a PRL starting with 51 on Sprint but thats what my iPhone uses. Quote Link to comment Share on other sites More sharing options...
fubka Posted June 13, 2012 Share Posted June 13, 2012 Pretty sure I remember reading that txts are sent out over 1xrtt and that the phone actually bumps back down to 1xrtt to send a text or a voice call? So if it is already on extended roaming (1xrtt) there is not change, if you are on 3g (EVDO) it has to change? Quote Link to comment Share on other sites More sharing options...
