I can't send a message on Android. Android does not receive SMS or does not send them

This afternoon, I did my business in the city, sent my wife an SMS, threw the phone into my bag without looking and drove home. Arriving home, I again automatically sent my missus an SMS message that I was already home. After some time, my wife calls me and the following dialogue occurs:

Are you already at home?
- Yes, I sent you an SMS.
- I didn’t receive anything from you...
-Have you sent me any SMS?
- Yes, a list of products.
- Hmm... (I didn’t receive anything either)

I turn on the phone (Samsung Galaxy Note N7000), I open the history of SMS messages and see that there are no (!!!) messages that I sent.

I type a new SMS message, click “Send” and before my eyes the message disappears without getting into the history. I start to panic and think about what could have happened. At first I thought that the problem with SMS most likely arose due to the settings of the SMS message center on the phone. You never know, maybe it got lost for some reason or the number of this SMS center has changed. I called the operator and found out that nothing had changed, my SIM card it works fine (I can call) and they don’t see any problems on their part. They still advised me to understand the phone and read the documentation :-)

In general, in order not to languish for a long time, I will say right away that everything turned out to be painfully prosaic - in the SMS settings I had a limit of 200 messages for one dialogue. After increasing this limit, everything worked as before.

To get into the SMS message settings you need (screenshots taken on Samsung Galaxy Note N7000):

1) Go to messages - a window in which you can see a list of all SMS dialogs (an icon with an envelope and the signature “Messages”, second from the right):

2) Call up the menu and select "Settings":

3) In the settings, select "SMS Restrictions":

4) Change the value to 999:

That's all, actually. And don’t forget to periodically clean the dialogues.

I was most surprised by the behavior of my beloved Galaxy Note - it did not warn that the SMS message would not be sent due to restrictions, did not issue any warning message, did not even place SMS messages into the story with red exclamation point(as happens with network problems). Overall, I think this is a seriously flawed piece of software.

I think that such a situation may be faced not only by Samsung owners Galaxy Note N7000, but also other devices, like N7000, S, S2, etc., running Android.

Modern mobile devices are little assistants that give us the opportunity to exchange information whenever and with anyone. Some people find it easier to call, others prefer to use it for communication. social media, but there are also those who prefer to use SMS.

Depending on the tariff plan, which you use, or the terms of service of the mobile operator, SMS messages may not be sent precisely because there is not enough money in the account. Owners of contract accounts and service packages should check with the operator whether the specified service is activated.

Check the recipient's number
The problem may have occurred due to incorrect specified number recipient. Try sending the message again, and if the attempt is unsuccessful again, contact the mobile operator's support service.

If the phone is on the platform Windows Phone or you iPhone owner, you should go to the settings of the phone itself. Then select and replace (if necessary) the number with one of the following major mobile operators in Ukraine:

2. MTS (Jeans, Ecotel) – +38050000501.
3. Kyivstar (djuice, Mobilych) – +380672021111.
4. Beeline – +380683201111.

The problem may be with your SIM card
The reason for the inability to send SMS may be due to mechanical damage devices or SIM cards. Another reason is moisture getting inside the device, which led to oxidation of the contacts. Also from long-term use The contact between the phone and the SIM card becomes weak. Then you need to go to the salon cellular communications, where you will receive a new SIM card. The numbers from the old card do not disappear and are saved.

Mobile operator server

This is due to the fact that people from all over Ukraine and abroad are trying to simultaneously congratulate each other on the upcoming holidays, which causes temporary technical problems with an overloaded server.

Other reasons

• Restart your mobile device and try sending the message again.
