Xperia z fails to send multiple sms, when failed sms are re sent phone says successfull but recipiants say not so

[ben_coy4_gmail_]

Hi,

I have purchased Two xperia Z's for our business, which relies heavily on communication.

my partiner often needs to contact multiple people via sms.

upon sending "Bulk sms" up to 50 recipients, the phone displays a message saying something along the lines of "Messaging is sending a large number SMS messages. do you want to continue sending messages" then when you allow it to continue all further messages fail.

if I then go to the failed sms and re-send the phone says successful, but the recipients do not receive the message.

Please Help.

is there a problem with the way the phone ques the sms for send?

is there something locally on the phone that could be causing this to happen

Note: the phone has -95dBm 10asu signal strength, UTMS, 100% battery, android 4.1.2

this is causing a lot of stress and is disappointing as our old arc s phones were much more reliable at this task. (occasionally failed)

Im also having issues sending multiple texts....... i had an xperia arc which allowed me to send as many texts as i wanted to a group of 50 at a time (3 groups of 50, each text approx 3 message lengths long) with no issues. I then moved onto the xperia L which had the issues mentioned in this thread and now i have upgraded to Z1 compact which has the exact same issue! very frustrating as i rely on it for my business. I need to solve this! I will not have sony phone next time if this cannot be done.

Hello,
I am having the same issue as mentioned above. Upon texting beyond a certain number in a short time, I continually get the prompt to allow or deny texts to be sent.
Has Sony replied to anyone directly offering a solution?
Thanks,
Taylor
