SMS is not received by the international recipients

Is it best to check whether the phone numbers are entered in the correct format? So no 0 in front but e.g. for India 0091 or +91.

If the problem persists, I would contact customer service.

sms is sent directly via banking app but in the inbox I can see that they have sent it to +91...…

for the test purpose, I also sent a sms to family members using +91 and problem is the same.

Okay, that's really weird, maybe you should call customer service. It is also available in English.

You can reach him on the following phone number

Hello @siddharth2022 ,

welcome to the community. 
Can you send SMS to other recipients? Also to foreign numbers? 
What type of cell phone do you use exactly?

Best regards,

Maria

Hello,

Sms is sent to different indian numbers but none of them receive it.

I can send sms to German number and all German numbers receives my sms.

I really see it as a technical problem from O2 side.

I am using android phone ( oneplus6t)

all the settings are correctly set.

Hello @siddharth2022 ,

Thanks for your feedback.
Can you send SMS to other foreign numbers?
Can you call Indian numbers with your cell phone?
Have you checked if there is a block on calls/SMS to foreign countries in your phone?

Best regards,
Maria

I can call to indian numbers.

msg is sent from my phone and money is also deducted.

only the point is, none of the recipent from india receives the msg.

Hello @siddharth2022 ,

Can you find out if the recipients of other SMS from Germany can receive?
Do you have the possibility to test the sim card in another cell phone? Whether it works there with the SMS send to India.

Best regards,

Maria

Hello Maria,

I received reply from O2 and its hopeless! :/ 

Before raising compliant here, I already check all the other things! I am sure, this issue is from O2 and I think, I need to take further action against O2.

Lieber o2 Kunde,

auch nach intensiver Prüfung (Nr. P*********) konnten wir keine technische Beeinträchtigung unseres Netzes feststellen. 

Ggf. gibt es andere Gründe für die von Ihnen festgestellten Einschränkungen.

Hilfreiche Tipps finden Sie unter: https://hilfe.o2online.de/welcome

Freundliche Grüße, Ihr o2 Team

Hello @siddharth2022 ,

Thanks for your feedback. 
I have also just received this message.
Our colleagues in the technical department have checked everything and there is no malfunction on our side. 
I don't really have any more options for action here. 

 The recipients should contact their local provider and ask whether there are any restrictions on reception from the German network.

Best regards,
Maria

​@o2_Maria 

it has been 2 years and issue is the same. :(

Hello ​@siddharth2022,

that is unfortunate, when once again SMS from you cannot be received in India. 

OIf you also could not send SMS to the numbers of friends and family, could they already check with their providers whether there are any restrictions receiving on reception from the German network?

Best Regards,

Gerrit

Hello Gerrit,

Thank you for your response.

Yes, unfortunately, none of my SMS messages are being received by friends or family in India, regardless of the Indian network they use (including Jio, Airtel, and Vi). I have asked them to check with their respective providers, and there are no known restrictions or blocks on their end for receiving international SMS.

Given that the issue has persisted for years and only seems to affect O2 prepaid (while O2 postpaid worked in the past), I strongly suspect this could be a routing or configuration issue on the O2 side.

I’ve also contacted O2 support and reached out to Bundesnetzagentur (BNetzA) for further investigation. Still, I would really appreciate if your team could escalate this internally to the technical department for a more thorough check.

Best regards,

Siddharth

Hey ​@siddharth2022,

it seems like we kinda missed this post of you - I’m sorry, now it’s on my desk and i will try to see what’s happening here. 😊 

Can you tell me which provider your friends in india are using? Maybe there is a connection why it is not working. Otherwise i have to ask some colleagues and do some research in order to find the answer - but we will stick to it now. 😄

Hey ​@o2_Paul 

thank you for the message. I have tried to send sms to all kind of service providers includes -

BSNL

Airtel

JIO

Idea

the problem exists for all!
