Despite the fact that every­one around uses Inter­net mes­sen­gers, some­times you need to send or receive a good old SMS. At least in order to log in to What­sApp or Telegram. It may hap­pen that mes­sages are nev­er deliv­ered to the sub­scriber. We under­stand the rea­sons why SMS do not come and are not sent from the phone.

Why do not SMS come and what to do

The caus­es of prob­lems with SMS deliv­ery can be hid­den both in the mobile phone and in the SIM card. A ser­vice engi­neer for the repair of equip­ment will help us fig­ure out this sim­ple but tricky issue. Artur Tuliganov. Let’s start with com­mon­place things that are easy to fix.

1. Not enough free space.

Per­haps only own­ers of old push-but­ton phones can face such a prob­lem. The fact is that in these mod­els the amount of free mem­o­ry is lim­it­ed, so new mes­sages sim­ply “do not fit” into the phone. The solu­tion is sim­ple — delete unwant­ed mes­sages from mem­o­ry.



2. Cellular network congestion.

Yes, that can’t be ruled out either. This can hap­pen at the moment when all sub­scribers start using the net­work at the same time. For exam­ple, imme­di­ate­ly after the New Year, every­one is in a hur­ry to con­grat­u­late their loved ones. But it is worth wait­ing 10–20 min­utes and every­thing will return to nor­mal.

3. Problem with the SIM card.

For some rea­son, there may be prob­lems with the con­tact of the SIM card and the phone. To exclude this pos­si­bil­i­ty, insert a known work­ing SIM card into your smart­phone. If the prob­lem with receiv­ing SMS remains on this num­ber - take the device to a ser­vice cen­ter. Most like­ly, the mat­ter here is in the hard­ware of the device.

4. Messages end up in spam.

Your phone may have an auto­mat­ic fil­ter built into it that blocks received mes­sages as spam. Tem­porar­i­ly turn off the mes­sage fil­ter­ing func­tion in the mes­sage set­tings and check if you receive mes­sages. If yes, then turn off the spam fil­ter per­ma­nent­ly.

5. The interlocutor was in the “black list”.

Tech­ni­cal­ly, the sit­u­a­tion is sim­i­lar to the pre­vi­ous one, only mes­sages from one indi­vid­ual user remain in the block. A con­tact may, for some rea­son, be black­list­ed on your phone and all mes­sages from him will be blocked. Check if there is a sub­scriber from whom you can­not receive mes­sages. If yes — delete this num­ber.

6. Messages are blocked by the installed application.

And again, the soft­ware of the smart­phone will be to blame here. It is like­ly that you have installed some kind of pro­gram designed to pro­tect your smart­phone from crooks. An over­ly aggres­sive fil­ter will block all mes­sages it con­sid­ers sus­pi­cious. The solu­tion to this prob­lem is sim­ple -dis­able or unin­stall all secu­ri­ty apps from your phone.

Why are SMS not sent?

The rea­sons for which SMS may not be sent may be sim­i­lar to those for which SMS are not received. But there are also some dif­fer­ences. Let’s start with the sim­plest again.

1. Wrong number dialed.

We send SMS not so often, so be sure to check the cor­rect dial­ing of the num­bers of the num­ber. The sub­scriber num­ber in Rus­sia can begin with the num­ber “8” or the char­ac­ter set “+7”. Next comes the three-dig­it oper­a­tor code and the sev­en-dig­it sub­scriber num­ber.

2. SMS is not sent after changing the SIM card.

It often hap­pens that after chang­ing a SIM card or an oper­a­tor, users notice odd­i­ties in the oper­a­tion of SMS. And it’s not just that. The sys­tem delib­er­ate­ly blocks received and sent mes­sages so that crim­i­nals can­not imme­di­ate­ly access impor­tant infor­ma­tion, even if they man­aged to “hijack” the num­ber. Usu­al­ly the unit turns off a day after oper­a­tions with a SIM card.

3. SMS are not sent due to lack of money on the account.

It often hap­pens that after pay­ing the basic tar­iff, there are no funds left on the sub­scriber’s account to pay for send­ing SMS. Check the bal­ance in the oper­a­tor’s appli­ca­tion or code “*100#”. If there are not enough funds, then pay the required amount or con­nect an unlim­it­ed SMS pack­age.

4. The number for sending SMS is not configured.

Before being sent to anoth­er sub­scriber, the SMS enters a spe­cial “gate­way” of the oper­a­tor, the num­ber of which is auto­mat­i­cal­ly con­fig­ured when the SIM card is reg­is­tered on the net­work. Some­times the num­ber of the SMS cen­ter can be filled with an error and because of this, SMS are not sent.



You can view the SMS cen­ter data in the mes­sage set­tings menu. Each oper­a­tor has a dif­fer­ent num­ber, so it will be eas­i­est for you to find the one you need by search­ing the Inter­net — “SMS cen­ter num­ber + name of your mobile oper­a­tor”. If you find out that the num­ber of the SMS cen­ter in the phone does not match the one indi­cat­ed on the web­site of the oper­a­tor, call the sup­port ser­vice. By the way, the same applies to MMS set­tings and mobile Inter­net. They auto­mat­i­cal­ly reg­is­ter the address­es of APN access points. Some­times these set­tings can “fly off”.

5. You are in the “black list” of the subscriber.

Alas, mes­sages from your num­ber can be blocked (on pur­pose or acci­den­tal­ly). You can­not do any­thing with this. It remains only to ask the per­son to whom your SMS does not reach, check the “black list” and remove your num­ber from there if nec­es­sary.

6. Operator blocks SMS.

Due to the fact that through mes­sages you can access finances, most oper­a­tors can block the func­tion of send­ing SMS to short num­bers at the request of the sub­scriber. Also, sim­i­lar restric­tions are found in some cor­po­rate cel­lu­lar tar­iffs.

To make sure your mes­sages are not blocked at the oper­a­tor lev­el, con­tact cus­tomer sup­port.

Popular questions and answers

Can I get a virus on my phone via SMS?
You can’t use the SMS itself, but you can use the link in it. Scam­mers can send you the address of a dan­ger­ous site under the guise of some­thing use­ful. For exam­ple, dis­counts and coupons to the store. There­fore, nev­er click on links from such ques­tion­able mes­sages. The same applies to the “pranks” from What­sApp chats.
Is it pos­si­ble to block the receipt of SMS from a spe­cif­ic sub­scriber?
It is pos­si­ble, and at least in two ways — through the phone soft­ware and through the oper­a­tor. In the first case, you add the num­ber of the blocked sub­scriber to the “black list” of your phone. In the sec­ond case, you do it through your car­ri­er. Block­ing via smart­phone remains prefer­able — it’s eas­i­er to set up and it’s always free.
