SMS are not sent

o2_Tobias that does not make any difference. When I input "+491760000443" and then "Update, it's ok. When I hit "Refresh", it's again "+491760000443",145

And that is not an error. See this:
https://www.developershome.com/sms/cscaCommand.asp
"The address_type Parameter"
145. Meaning: The SMSC address is formatted using the typical ISDN / telephony numbering plan (ITU E.164/E.163) and it is an international number. Example address: "+85291234567".

145 was set as default when I made a hard reset of my phone so it probably got that setting from SIM or the network or whatever.

o2_Tobias thank you for the reply. Unfortunately, both solutions did not work.

When I put the SIM to another phone, it detected the SMSC number correctly automatically but I still cannot send messages either to +7 or to the local +49 numbers. Looks like there is an issue with the network.

I do have more details to add.

First of all, I've purchased a prepaid number and had been using it for a few days.

Then I came again and purchased the unlimited traffic contract (that one 60 euro per month) and asked them to save the number.

I've also asked for additional SIM card so I can use 1 card in the Huawei router (purchased in the same o2-branded shop) and another card in my smartphone.

They said that it would cost me +5 euro/month - okay.

They inserted the original SIM card to the router and made it data only. It works fine and I've been using internet and sharing it at my home.

The additional SIM card they gave me, had another number. The actual number migration completed on January 30. SMS never worked. I used to think that I needed to wait until the number migration but it did not change anything.

The problem is the support is German only and I've just arrived in Germany 2 weeks ago and have not learned German yet.

Hi @OlegN,

for what reason do you need the ticket-number?

If you need a record, just refer to our communication here in our English community.

Thanks a lot for your understanding.

Loving greetings,

Hi OlegN,

I can send you the ticket number, regarding this issue, via private message, but firstable I need further customer data. Do you want me to send you a message or is it okay if I just tell you that that it had something to do with a missing option in your tariff?

Best regards :)
