BlackBerry Z10 LTE Drop on phone calls

I'm on the Bell Mobility network in city Edmonton Center with my Z10. I still have an LTE coverage for my Z10. When I run a phone call he begins in LTE with HD Audio then immediately falls to the HSPA network +, for the duration of the call (and I lose the HD Audio). LTE is good once I disconnect the phone call. For the phone call, I'm not walking but stay in the same place. I do not use my phone or also travel a lot so I don't have a lot of different scenarios to see if this is everywhere all the time. Has anyone else noticed temporary fall of LTE network while in voice calls?

I got a little more guidance on what happens here through some contributors of Crackberry, so I wanted to share them here too. Voice does not work on the current LTE network - that is to say LTE is just for the data so that HSPA + is for voice. So by default when you start a voice call unit must always go down to the HSPA network +. HD Audio works on the network, HSPA +, but you will have to call another device supporting it. More particularly the more advanced of iPhone5 Android and other Z10 devices. HD Audio does not work when it comes to fixed lines.

In my scenario, it seems that everything works fine. I rarely call other cell phones (in general I call fixed) so it'll be hard for me to 'test' and provide additional comments.

    Hello

    I agree with @JSanders , once it is dry that the BBID is therefore more about Fanta devic, you can start the original game from the phone to the new BBID on it.

  • BlackBerry Z10 menu drop-down ("Notifications", "Alarm") disappears!

    My z10 works beautifully.

    Except in the last days whenever I do the drop-down list active (the one accessible by sliding from senior management downwards) and try to click "Alarm" or "Notifications", the menu drop down menu scans back and disappears!

    In other words, it seems that * just * these two buttons (alarm and Notifications) are disabled, so the effect is the same, as if I was to click on the black background of the drop in the menu drop-down or anywhere else but an active button. By pressing the buttons or notifications in all sorts of ways has the same effect: the banner just think you want to exit the menu and disappears.

    Any ideas why this happens? Am I the only one?

    I had to return the phone and get a new one.

  • BlackBerry Z10 not love my phone after the update

    I have a BB Z10, STL100, software model shows that 10.3.1.1581

    Last week, I received a notice of update, insstalled & restarted.  I've hated since then.  Once I log in, my screen moves to the right and is too large, I reduced manually each time. Tried to change the font sizes, doesn't change anything.

    Miss me appointments in my calendar, because now I get is more notifictations sound and I wouldn't change a thing.  I also can't find anything in the settings to get it back.

    I'm close to the end of my contract with my service provider and a bit of dumping my phone instead of upgrading to another BB, had my eye on the Passport, but if I'm not in meetings or appointments.  This will change.

    DRM for any help

    Question 2: Is usually resolved with a battery pull.  If it does not try to change the ringtones for the calendar application in your active profile.

  • BlackBerry Smartphones * or # when a phone call is not recognized

    Need help!

    Sometimes, when I am on a call and asks me to enter my account number, and then press the book, I enter my account number and then press [alt] [Q]. However, it is not to recognize the # sound being pressed. Some companies will let you just enter the number of account and then assumes that you have completed, but I came across one who keeps asking me to enter the account number, and then press the book.

    I also have the same question when I call my home phone and I need to support on * to access my voicemail. I press [alt] [A], and it keeps telling me that I entered an invalid option.

    I would appreciate any suggestions or messages.

    Thanks in advance

    Press on the * /A key, with NO pressure on the ALT key.

  • BlackBerry 8320 Smartphone restarting during phone calls!

    My first curve from T-mobile returned 1 day later.  During this time it restarts to 50 times.  Obviously defective.

    The other do not restart, but the right button was almost impossible to grow.  He returned and got a warranty Exchange.

    The third curve works well 95% of the time.  But a few times a week, it recharges during a telephone conversation.  He doesn't do it anytime (unlike the number 1 of the curve).  It is extremely annoying.  I had high hopes that the new operating system could solve this problem, but no luck.  He always does.  You are looking for a "reboot call curve" on google Gets a LOT of success.  Thus, it is clear that I am not alone in this.  I read everything I can find on various forums, but nobody seems to have a definitive cause or cure.   I tried to remove the memory card, reformat the memory card, replacing the SIM card, restart the device manually, obsessively check the free memory space (no problem, I have 20 or free), exchange the battery, etc, etc... and she always does.

    It always seems the case in the first minute of the call.  This happens when you are logged on BOARD and UMA.

    I'm not going to downgrade or wipe the device because there are more messages from people who have tried it and I have yet to hear that it worked.  In addition, he did before the OS update so I have no reason to suspect it.

    I called T-mobile, and they claim that they have never heard of such a thing, which is questionable.

    This weekend, I reformatted the card again.  The next time that it restarts, I call and ask the curve number 4.

    I'm very disappointed with the quality of these things!

    As you say 'Tough luck for this forum'... .and your attitude

    Good luck!

    Thank you

  • iPhone 6 + guard passing phone calls

    Since last week, my iPhone 6 + guard drop in phone calls. And a few times when I call back it will ring once and then down the call once again.  Should I take my SIM card to clean or?

    Hello bhetherington7,

    Thank you for using communities of Apple Support.

    I see that you are having problems with your iPhone dropping calls. Take a look at the following article to get suggestions to try for that matter. Some steps are not applicable to your particular issue, as turn airplane mode on/off or check the settings for do not disturb. Most of the others are, like updates, removal/reinsert the SIM and communicating with the carrier.

    If you can not make or receive calls on your iPhone

    Best regards.

  • 10.2.1.537 Z10 post upgrade Blackberry Z10 OS blackBerry-phone call does not

    Dear team,

    I have updated to OS 10.2.1.537 today morning post updated and I'm not able to make phone calls. On the choice of the network, I am able to select the required network (Airtel India) but not able to make phone calls. Neither the data service works. SMS message also works using the telephone network, but not the call. Tried restarting, remove the SIM and the battery without any improvement.

    When you try to call I always get the message "the cell phone line is not available. Choose a different phone line and try your call again.

    concerning

    Surya Roy

    Hello and welcome to the community!

    10.2.1.537 is, in relative terms, a very old operating system level... you really need to use something more current, especially given your model Z10. I recommend that you force a reload of BONE via the more energetic method... ADF:

    Remember that you you get the AutoLoader for 10.2.1.3247 because it contains some very important fixes for the Z10 specifically.

    Good luck and let us know!

  • Monthly data of blackBerry Z10 and call usage limit check and alert

    Hi team,

    With BBZ10 we are missing to have alert and the limit control for the use of the data and the use of the phone call.

    This seems to be a fundamental characteristic for any smartphone to live and android already supports this.

    Most of smart phones is purchased with contracts that have limited the use of the data and phone call.

    Please update if no development or a solution on this.

    Thank you

    Ravindra Dolas

    Hello ravidolas,

    Thank you for your question. You're right, that's not a feature of the BlackBerry Z10. Your mobile service provider can offer that service, then I would say that contact you them for more information. I want to thank you for your comments. We value your feedback as we work constantly on improving our products.

    Nice day.

  • Lost blackBerry Z10 phone

    Magalie

    Today, I have a bad day. I lost all the money this month (I'm a student), and the worst is that I lost my blackberry z10 . When I knew I lost it, I was very angry.although it is an old phone, I purchase form someone else, but with me, it's a treasure and a friend. I'm going to protect.blackberry.com, then replace 'Flag as stolen', because I want the thief have only a brick. but now I think that if the thief do not turn the data or does not connect with a wifi then sell it to another people. It is verry bad for them. They lose money from verry for a brick. (I live in vietnam, security is not high, I don't want to aggravate some for someone, but I don't want someone not know my data on my phone, I install 10.3.2, I don't know what happens to my data on my SD card, I want to, it can be earsed).
    You can check what is happening with my data, as it can be not to connect to the internet.
    Thank you verry much!

    Oh sorry for your loss!

    Your inserted SD card is not affected by Protect or whatever it is. To protect your card data SD Media you would have needed to have the encryption on the card.
