It should. Go to settings>general>about and scroll down to the "Carrier" field. What does it say?

I'm on Sprint 25.0, PRL 54056.

 

Maybe only the 6 and above get SMS over Wi-Fi?

Possibly...if you're on wifi and you keep clicking that field until you get to "IMS Status" what does it say?

Ha, it says Voice & SMS. Guess it was just a glitch earlier. :-)

So is that strictly SMS or is it SMS/MMS? I have several family members who would be really happy if it is also MMS...

So I thought I had read somewhere that with iOS 10 you'll be able to go from wifi calling to the sprint tower network seamlessly. Is this the case? I would actually use wifi calling if it worked like that instead of just dropping the call if wifi strength drops...

I believe that is only possible once VoLTE is enabled, which is likely years off for Sprint.

I'm 98% sure that WiFi to CDMA handoffs are working now. Don't quote me on that though, as I've never tested it, but I remember reading it after we discovered the WiFi calling changes in iOS 10.

That would be HUGE and would lead me to keep wifi calling on all the time. It's too glitchy otherwise

Sprint has adopted the Wifi Calling standard that apple uses which is pretty much mostly based on the well known and adopted 3GPP standards. That's why recent android devices could not do SMS over WiFi as they don't use the old proprietary IMS core. 

 

The new wifi calling implementation will allow WiFi calling to CDMA soft handoffs.

Really? Has that been verified yet?

By me :). It does not always work though. I want to say it's worked about 70% of the time on my iPhone 6S.

(On your iPhone) Tap first profile in the list, install it, and the iOS 10 GM will show up in Software Update after a reboot. No need to wait! Delete the profile after iOS10 has loaded and you'll be all set. 

 

This is next Wednesday's release, so it's not cheating. 8-)

Why did it switch to CDMA when voicemail took over? It looks like it was still connected to Wi-Fi during the call, was there a reason it went to CDMA instead of the call staying on Wi-Fi?

 

What I'd like to test is making a call, then slowly walking down the street until my phone drops home Wi-Fi to see if it still stays connected.

The phone determines when the wifi conditions are inadequate and hands you over accordingly from my observations. I purposefully went into a room with a sporty wifi connection.

I think it's too much of a coincidence that it switched to the Macro network as soon as the call connected, though. I guess it just didn't seem like a "handoff" in the video, it just "switched" before the call began.

I just went outside and started a call on wifi, then walked away from the wifi while talking to someone. It became spotty and eventually I got the Call Failed message. No handoff.

 

iPhone 5C, Sprint 25.0 Carrier, iOS 10.0.1. 

 

Has anyone else tried this type of scenario yet? This seems like the most common situation, like receiving a call in the garage on wifi, then driving away from the house.

Just had a call between two phones on Sprint Wi-Fi calling w/iOS 10.0.1 and the HD voice was perfect. So that's working!  :tu:

I've tested that. It works seamlessly. MMS does not work though...

Anyone use YouMail that can test to see if that works now with WiFi calling?

      I don’t know if anyone has already posted information about wifi calling, so I thought it would be good to add this.  In the last 2 weeks, I posted on the sprint.com forum and the Sprint reps were unable to answer the simple question of what port does wifi calling use. Previous to posting I called customer service and Airrave support and no one could answer either. I didn’t expect a detailed answer, but they could have called someone who knew the answer.  Anyway, two very knowledgeable users on the forum narrowed things down, and wifi calling uses UDP port 4500. I had already narrowed down the ports to a handful, since I found information on the web about TMobile’s similar wifi calling. Also, I found a netstat option built into my Asus RT-AC66U router that was helpful for looking at ip/ports for our phones. The Sprint server the wifi calling traffic heads to is 68-31-26-1.pools.spcsdns.net  The reason I started asking about the port and connectivity is because we experienced many calls that would either drop or when you called someone it would go silent during the call. This goes along with UDP traffic being connectionless and sensitive to any disruption.  I prioritized traffic for our GS4T and GS5 phones for port 4500 and found there was a firmware updated from Asus for the router that helped.  Also, I skimmed over (on some other android forums) the updates for the GS5 to android 4.4.4 and I noticed something with wifi calling bug fixes.  I am happy to say that the wifi calling is working a lot better now.

      So, we all know about the lovely iPhone 6 and iPhone 6 Plus User thread, and there are many different device focused threads across S4GRU, but there are none for us older iPhone users. So, why should they get to have all the fun? This thread is dedicated to anything and everything about our beautiful (Spark-less) iPhone 5's and 5S's.
       
      Discuss anything like jailbreaks, hardware problems, how much you love your device, how great it is to have at least one LTE band compared to the folks who still have 4's and 4S's, ask questions and maybe you can get some answers, etc. etc.
       
      Discuss!

      I know someone on here might be able to help, but I have a Sprint iPad mini (1st gen) and I have been swapping between my Sprint SIM card that came with the device and a TMobile SIM. This past time when I reinstalled the Sprint SIM I was able to purchase data, but then the reprovisioning kept failing. I cannot use the data. I tried resetting the iPad completely, and that did not work. I restored the iPad as new and that also did not work. I also noticed that the iPad kept going from Sprint 3G to 1x over and over, even in an area with full LTE. I called Sprint support and they said that they could not handle anything prepaid (which was shocking), but when I pushed a bit on them, they helped troubleshoot. Still, nothing has worked. I will call Apple this evening if nothing else, but I am traveling for Memorial Day, so it would have been nice to have extra data on the iPad. Anyways, does anyone have any thoughts? I am thinking it may be a hardware issue, but it does not appear to be a SIM card issue. Still in the car on a long trip from NYC to Ohio for a wedding reception and visiting the in-laws.

      With the FCC and Sprint, T-Mobile, AT&T and Verizon have agreed to this new unlocking policy. How does this effect sprint phones such as the IPhone. I have heard that Sprint can unlock your phone but you can not take it to other carriers such as Verizon and the IPhone can only be used overseas.  (Correct me if I am wrong). I am glad that this has finally happened. But when it comes to Sprint how would this work?

    • I am definitely interested in checking more into this phone. Am I correct in assuming all phones being released from this point on (before now, really)  are HPUE compliant?
    • You literally said #2 carrier ahead of AT&T. They're #2 not because of network metrics but because of the amount of subscribers they have. Nationally, they're still ranked last in terms of overall network performance because despite their square milage, they still lack in call and text reliability. There is zero doubt that they have one of, if not the fastest network in the country but that is far from the only metric to measure a network, even if it's the most important to you. All you have to do is look at the recent reddit thread that suggested T-Mobile might stop their program that gives people those Cellspots to see that a lot of people were ready to switch because the only thing keeping them on was that device giving them service indoors. At least we know Sprint is going all in on the Magic Boxes and they treat it as a part of their network instead of as just another device.
    • Nothing to do anything about number of customers... How are they not on par with the big two?  TMobile is crushing it for data in all the major markets.  If TMobile can execute their 2017 coverage map goal, they will be on par with AT&T, which is considered to be in the same coverage league as VZW.  So yes, TMobile will be in this club come 2018. https://www.t-mobile.com/coverage/lte-comparison-map
    • This is a reach. AT&T and Verizon still have twice as many customers as T-Mobile and even if they added 2 Million customers per quarter it would take 8 years before they got to VZ and AT&T's current size, assuming VZW or AT&T don't have any growth at all. We can acknowledge T-Mobile's accomplishments without making it seem like they're nearly on par with the big two. In terms of data speed, sure. In terms of price, they're approaching it too. However, you won't be able to find the consistency of the duopoly's network nationwide on T-Mobile right now. That'll take quite a bit more infill sites. That's why given Sprint's "non-announcement" of 8K macro sites for expansion, I'm glad to see it's not a huge expansion because we know that they're going for reliability over square mileage.
