This repair is to replace the SIM reader. If a device is unable to detect the SIM card, then the chances are the SIM reader is faulty.
Please check the SIM card you are using is registered and on the correct network for the phone.
Water damaged Desire 510's are stripped and run through a cleaning process. Once a device has been cleaned, the main board is re-flowed. This will fix any damaged connections on the main board. This only costs £29.99 if successful, and £19.99 if unsuccessful. Repairs to liquid damaged devices are not always successful. If any parts of the device need replacing, we may need to re quote, without obligation.
If your device is running out of power quickly (compared to when it was new) and you are constantly having to put it on charge the battery may need replacing.
