Basic Text Message Fixes

Start with these simple solutions that fix most messaging problems

1

Check Network Signal

Text messages require adequate signal strength to send. Check your signal bars - if they're low, try moving to a different location.

Signal Tips: Higher locations, near windows, or away from electronic interference often have better signal for messaging.
2

Restart Your Device

Power off your phone completely, wait 30 seconds, then turn it back on. This clears temporary software glitches that can prevent messaging.

For most phones: Hold power button > Power off > Wait > Power on

3

Check Message Center Number

The message center number routes your texts through Tesco Mobile's network. An incorrect number prevents sending.

Tesco Mobile Message Center: +447802000332

For iPhone: Settings > Messages > Send & Receive > Check number

For Android: Messages app > Settings > Advanced > Message Center

Important: Don't change this number unless you're certain it's incorrect. Contact Tesco Mobile support first.
4

Check for Blocked Numbers

Ensure you haven't accidentally blocked messaging or the specific recipient.

For iPhone: Settings > Phone > Blocked Contacts

For Android: Phone app > Settings > Blocked numbers

Check APN Settings for MMS

MMS (picture messages) require correct Access Point Name settings. Incorrect settings prevent media messages from sending.

Tesco Mobile MMS APN Settings:
APN: prepay.tesco-mobile.com
MMSC: http://mms.tesco-mobile.com/mms/wapenc
MMS Proxy: 193.113.200.195
MMS Port: 8080

For iPhone: Settings > Mobile Data > Mobile Data Network

For Android: Settings > Network & Internet > Mobile Network > Access Point Names

6

Update Device Software

Outdated operating systems can have messaging bugs. Ensure your phone software is up to date.

For iPhone: Settings > General > Software Update

For Android: Settings > Software Update > Download and Install

Backup First: Ensure your data is backed up before updating software.
7

Reset Network Settings

This clears all network-related settings and can resolve messaging issues caused by incorrect configurations.

Note: This will erase saved Wi-Fi passwords and Bluetooth pairings.

For iPhone: Settings > General > Reset > Reset Network Settings

For Android: Settings > System > Reset Options > Reset Wi-Fi, Mobile & Bluetooth

8

Test SIM Card in Another Device

If possible, try your Tesco Mobile SIM in another compatible phone to determine if the issue is with your device or account.

Diagnostic Tip: If the SIM works in another phone, the issue is with your device. If it doesn't, contact Tesco Mobile support.
