iOS 7 CoreTelephony


Recommended Posts

So I'm looking through the new iOS 7 headers, and my eyes catch a framework I've never really looked through before- CoreTelephony. I've read here on S4GRU that Apple would be opening CoreTelephony up and allow access to more information about the cellular connection. I've been thinking about making a SignalCheck-like app for iOS, and I realized CoreTelephony is what I've been looking for. But all they give access to is the signal strength (in bars -_-), the technology (EVDO, LTE, 1X), and surprisingly, the cell id. No RSRP or anything. No band or frequency of the connection. Huge let down.


So, my only option would be to use the private APIs and release it on Cydia, but planetbeing already has that covered with Signal and Signal 2. :(

So what are the options for "cool geeky telephony apps" on jailbroken IOS?  And it's still early yet.  We don't have a final release of IOS 7 so it remains to be seen if more features or hidden features will be unveiled in the API.

It's possible, but I highly doubt it. I don't see why they would give the Cell ID, but not the band.  :pinch:

The Core Telephony framework been available and documented in the API since iOS 4.0.  However, Apple has only approved Apps using Core Telephony framework from carriers and not third party app developers.  If you look at the Core Telephony Framework Reference page in the iOS Developers Library you will find the documentation for the following classes:






I guess Apple change their policy and allows applications using Core Telephony from third party app developers. I'd be interested to see Sensorly developers will finally release an iOS app that works like it's Android counterpart.

    • Luckily, that hasn't arisen in my area where I am, aside from having B14 (well, ALL of AT&T signal) not work at all in Coosa county, Alabama. I wish there was a service for first responders that would go to ANY available carrier, provider, etc..and in the absolute worst case scenario, would give us service. I've been on an ambulance, trying to find an address, and my driver actually had to pull over and we pulled out a map book and tried to find the road using the "old fashioned way".. and that takes valuable time away that sometimes may be vital to someone surviving. BUT, I will say that I've only seen that in Coosa county... both my Tmo and AT&T phones had zero service and I couldn't get GPS, and neither could my driver (VZW service). Maybe satellite will help with that in those times where that occurs.. but that's an extreme example.     Edit to add: Let me add some context to this.. Coosa county isn't regular coverage area for my job.. so it's not a regular thing that we are dispatched to Coosa county.. and actually, there's been a change and that county now has it's own ambulance service that operates.. so the only time we might receive a request is if it's a multiple casualty scenario, or it's a transfer going home from our contracted hospital.  The way that reads above, it may seem like we are just out without some sort of GPS gadget to direct us on where to go, but for the most part, we know our coverage area pretty well. Dispatch can also give us cross streets for reference inside our coverage area (and our home county). Coosa just isn't a regular area for my job to run in. 
    • "Priority" doesn't mean "exclusivity."  When emergency services don't need B14, AT&T can use it for everyone else.  The trade-off is that when it is needed for emergency services, they not only get all of B14, but they have also arranged for priority on the rest of the AT&T network as well.  Beats having spectrum sitting unused most of the time and then not having enough when disaster strikes, as it could be without a partnership with a wireless company like AT&T. - Trip
    • I've wondered if being on the first responder plan has the priority over other 'regular' lines in the same way firstnet does (or, supposed to do with B14...I've seen normal customers on AT&T hit B14 so it's not {specifically} for Firstnet only)...  
    • T-Mobile prices people pay are all over the map. The free lines are key, so take them if ever offered again.  Your priority level would be a key factor for your price.  Only T-Mobile would know the average prices people pay.  Samsung has been offering very good deals at time of new model introductions so I have gone that route for factory unlocked, which allows me to also have a Verizon priority MVNO for when T-Mobile signal fails or I manually override.
    • I also wanted to post a speed test result.. I only do these once in a while from my home area because we are gonna be the last to see changes, like load balancing.  Right now they are digging all over the place for fiber installs, so I'm not sure what the hold-up is on making the upload speed a little more in-line with download speeds, but here is the most recent from my area:   https://www.speedtest.net/my-result/a/10133670525
