What should I do if I cannot send or receive SMS on my Samsung Phone?
It is often a problem with the carrier or its service if you are experiencing difficulties sending or receiving messages or if they appear sluggish. Other times, if you recently moved from an iPhone, iMessage may still be activated, which might cause texts to be lost in the ether.
Check to ensure that your account is in good standing and that your service is operational. You should contact your service provider.
Make sure you have an active data connection to your carrier. Temporarily disable Wi-Fi and check for at least a 3G signal in the status bar.
- Open Settings, then browse to and tap Apps.
- Locate and then tap Messages.
- Tap Storage.
- Tap Clear cache.
Rebooting your phone will allow it to reconnect to the mobile network and clear up any temporary app difficulties preventing messages from being sent.
- Swipe down with two fingers from the top of the phone to access Quick settings.
- Select the Power icon.
- Tap Restart twice, then Restart again.
Check that the SIM card in your phone is properly placed and not damaged. If you need assistance testing your SIM or purchasing a replacement, contact your carrier.
- If you have another active device on the same network, you may be able to test them by exchanging SIM cards.
- If you recently switched carriers but continued to use the same phone, you may need to contact your current carrier for help reprogramming the phone for their service.
- On your device, navigate to and open Settings.
- Swipe to and then tap Software update or System updates. It will vary between models.
- Tap Download and install, or Check for software updates. If an update is available it will begin downloading, though you may need to tap Download now on some devices.

If your phone or tablet doesn't have enough storage space, you may free up space with Device care. You may also back up other files using Smart Switch or your Samsung or Google account.
