The article explains that not receiving SMS messages 24 hours after changing your SIM card is a security feature, not an issue. This measure helps prevent SIM fraud by blocking incoming SMS temporarily, giving the real owner time to report any unauthorized duplicate SIMs. If you’re experiencing ‘new SIM messages not working,’ this is likely the reason.
SIM Change and getting a duplicate SIM card for your existing mobile Number is not a big deal. But SIM changing or duplicating SIM taking in some countries needs some security checking and additional restrictions in some countries. Especially in India, you should know about the SIM changing procedures and the security measures taken.
It should be understood clearly that you will face the following issues after taking a duplicate SIM or while doing the mobile number portability. After exchanging or upgrading the SIM card, you may not receive any SMS on your new SIM card. Many users are used to logging complaints with customer care regarding this.
But it is not an issue with your operators such as Airtel, Vi (Vodafone Idea), etc. As per TRAI’s rule, any duplicate will not receive an SMS within 24 hours of activation. This will happen for BSNL users in some cases if the current 2G or 3G SIM card is upgraded to a BSNL 4G SIM.
A new rule imposes a 24-hour block on incoming SMS for all SIM cards to combat SIM fraud, where criminals duplicate SIMs to steal bank funds. This measure prevents fraudsters from receiving OTPs and other sensitive information during this period, giving the actual SIM owner time to report and deactivate the unauthorized duplicate SIM.
Incoming SMS Gets blocked after SIM Change
The new rule says that any duplicate SIM issued will not receive any SMS on that particular Number for the next 24 hours from activation. However, the outgoing SMS will work like before. You will also receive calls and can make outgoing calls, data, etc. The only issue is with the incoming SMS. It includes all the categories, such as personal SMS, OTPs, and other promotional SMSs.
How to Fix the Issue of Not Receiving SMS on Your Number
First, it is considered a security feature and not an issue. Hence, the resolution is automatic. The problem gets resolved automatically after 24hrs, and you will receive an SMS. For this, there is no need to contact or log a complaint with customer care. Just wait for one day, and things will get sorted automatically.
Reason For Blocking Incoming SMS after Upgrading the SIM
As per the new rule, the SIM card of any operator, whether Airtel, Vi (Vodafone Idea), etc., will temporarily ban Incoming SMS for 24 hours. This has been implemented to ensure the safety of the user. Several cases of SIM fraud have been reported, resulting in the loss of money from the Bank account.
Fraud action occurs in which thieves and criminals may take a duplicate SIM of users. The original SIM user will be unaware of this. Once a duplicate SIM card is issued, the original SIM with the actual person will automatically be disconnected. Further, all the calls and SMS will be received on the duplicate SIM card with the criminals. They can use this to receive OTP from banks to steal money from the SIM owner’s bank account. Since the number gets disconnected, the user will not get any information about this.
Such cyber fraud activities cannot occur during these times. To avoid this fraud activity, temporary blocking is implemented if you take a duplicate SIM. In the meantime, the original SIM owner can report the issue to its operators so that the duplicate SIM can be deactivated if the owner did not take the duplicate SIM.
Drawback of the SMS Blocking with the Duplicate SIM
The feature ensures the customer’s safety; however, it may cause issues for the original user. During the 24 hours, the user will not receive any SMS, including regular SMS, OTP, etc. If you are frequently using a bank account for online transactions, this might cause a problem. You will not receive any OTP from the bank to transact during these times. Also, if you are about to receive any vital SMS, you may miss them.
Another important thing is that you cannot register for applications such as WhatsApp, Viber, Duo, etc., using the OTP message during this time. Alternatively, WhatsApp and some other apps provide OTP over the call that can be used to solve this issue. But for all others needing OTP over SMS, you must wait 24 hours.
New SIM SMS Not Working
New SIM SMS Not Working is still an issue due to limited knowledge. Per the telecom regulatory rule, SMS service will be stopped for 24 hours from the new SIM activation. Then, after 24 hours, the SMS service will be restored automatically.
However, many people are still unaware of this rule and think it is an issue related to their Number and SIM. Nowadays, telecom companies are used to informing customers about this regulation, and an automated SMS will be sent to the customer’s mobile Number once the SMS service is restored.
Frequently Asked Questions (FAQ)
For the past few months, we have received several common questions via email, so we are adding the answers here.
Q: What should I do if my SMS settings are not configured correctly?
Double-check your phone’s SMS settings. Make sure the message center number is set correctly. If you’re unsure about the right number, contact Airtel customer support or visit their website to find the correct SMS center number for your area.
Q: Can restarting my phone help with SMS issues?
Yes, sometimes restarting your phone can fix SMS problems. Turn off your phone, take out the SIM card, wait a few moments, put the SIM card back in, and turn your phone on again. This simple process can often solve connectivity issues.
Q: Does poor network coverage affect SMS delivery?
Yes, having a weak network signal can cause problems with sending and receiving SMS messages. If you’re in an area with poor coverage, try moving to a spot with a stronger signal to see if that helps.
Q: What can I do if my messaging app seems to be causing the problem?
Go to your phone’s settings, find the app settings, look for your messaging app, and clear its cache. Clearing the cache can sometimes resolve temporary glitches that may be preventing SMS messages from coming through.
Q: Could third-party SMS-blocking apps be the culprit?
Yes, if you have any apps installed that are designed to block SMS messages, they might be stopping your messages from coming through. Try disabling or uninstalling these apps to see if that fixes the issue.
Q: When should I contact Airtel customer service for help?
If you’ve tried the troubleshooting steps above and you’re still having problems with SMS on your Airtel SIM, it’s time to reach out to Airtel customer service. They can help you troubleshoot based on your account and SIM card details.
Q: Do I need to activate an SMS pack when I get a new Airtel SIM or port my number to Airtel?
No, you usually don’t need to do anything extra to activate SMS services. When you activate a new Airtel SIM card or port your number to Airtel, the SMS pack should be automatically activated for you.
Q: Why is Airtel SMS Not Working After the SIM Change?
All telecom companies, including Airtel, have temporarily banned incoming SMS as a security measure. Once the new SIM is activated, the SMS feature will be disabled for 24 hours. After 24 hours, the blocking will be removed automatically. This option was implemented to safeguard the user from fraud.
Online fraud and illegal fund transfers were reported using the SIM Swap and the transaction OTP. After this implementation, fraud cannot take any duplicate SIM of the target user and hence won’t receive the transaction OTP.
Q: Why am I not Receiving OTP on Airtel?
If you change the SIM, you won’t receive SMS and OTP for 24 hours. After that, the blocking will be lifted automatically, and you can receive OTP as before. If you cannot receive OTP after 24 hours, contact customer care and log a complaint.
Q: How Much is the Airtel duplicate SIM Activation Time?
Per the company, the Airtel duplicate SIM activation time is 4 hours. But we can see that the SIM gets activated even before that in most cases. It can take around 2-4 hours in most cases. If your SIM is not activated after 4 hours, you can contact customer care or the retailer.
Q: Why am I not able to send SMS from Airtel?
If you cannot send SMS from Airtel after the SIM swap, you need to wait for 24 hours, and after that, the SMS feature will be enabled automatically. If you cannot send SMS from your Airtel number even without the SIM change, you need to check whether you have an active Plan available on your Number. If you have a plan, try to use the same SIM on another handset; if you can send an SMS from that, the issue might be with your handset. But, if you cannot send an SMS from another phone, please contact customer care and inform them about the issue.
Q: How to Activate SMS Service in Airtel?
May users are still asking how to activate SMS service in Airtel. Here, you need to know that the SMS service is already enabled on all the SIMs, and no special activation is required. However, the telecom companies recently introduced some new recharge plans that do not provide the option to send SMS. So, if you use a data-only or voice-only plan, the SMS feature gets disabled, and you can’t send any SMS using the Talktime balance.
On the other hand, it is also to be noted that if you have taken a duplicate SIM card, SMS service will be stopped for 24 hours. In that case, you don’t have to activate the SMS service manually. SMS service will be activated automatically after 24hrs.
The article is apt, to the point and cleared all my doubts…….All the best wishes team
Nice article kuch point clear hue but msg Kar bhi nhi pa rahe… Msg receive ka issue you tha hi
This should change… If it is the same owner. Y can’t u release the services… Has u take id proof of the person.. So that u can activate the sim
It is kept for an added security. There are cases happened before in which the duplicate SIM of the owner has been taken by fraud group in order to receive OTP after hacking their credit/debit card details.
To avoid this case, the no SMS period added for the duplicate SIM. But sure, it will be a headache for the real owner.
Absolutely, every time when you change the sim you have to provide your original documents so I don’t understand still how this fraud happens
After activating duplicate Airtel SIM card …..even after 22 hrs I can not able to send SMS…I understand about blocking the incoming messages for security reasons, but there is no point in blocking outgoing messages!
You can contact the customer care definity if the issue is there after 24hrs.
I was replaced my airtel prepaid on 30th may 2020 sim due to unable to send or receive any messages. Even I tried for porting that also not working..
Its Wonder till my problem was not solved 🤷♂️ so here if any expert candidate available can you please suggest what I can do??
Then some issue with you connection or phone. Hope you already tried sending message using another handset with your sim inserted. if not, please try that. Also make sure an active unlimited plan or any smart plan with enough balance to send SMS. However the incoming SMS should work even though u don’t have any plan active. You need to contact customer care for this issue if still persist.
Msgs received hi ni hore h but send ho rahe msgs .. kabtak thik Hoga ..
Normally it will be activated after 24hrs
I have changed handset but same problem coming and ur customer care number is not connecting can u pls help me because I m totally frustrated I m unable send port msg
If you have changed the handset and not the SIM card, there won’t be any blocking from the service provider. You need to check whether the SMS center number is correct. Also, to troubleshoot the issue, you can try your sim card on another handset (if possible).
Try to change your mobile phone
Nice u solved my isuue
Happy to hear that kiran.
thanks for the knowledge
its been more than 48 hrs and i am not reciveing any incoming message and the customer care is also not helping what should i do
In that case, it might be either an issue with the handset or from the network side. It is sad to hear that the Customer support team also not helping you. They are the ones who should look into it.
Please call the nodal officer in your circle and inform the issue.
This is idiotic. Even for a duplicate SIM, the stores ask for original ID documents and also take photo of the person who is being given the duplicate SIM. They why are they punishing the users? Should the user commit a fraud, are the photo and ID documents not used to trace the fraudster?
For all the services, they use the same verification process.
THANKS FOR ARTICLES. VERY USEFUL
