Vodafone Error 28: Unable to Send Texts? 5 Quick Solutions

Are you encountering a Vodafone 28 error and unable to send out text messages?

Vodafone error 28 usually indicates that either you or the recipient is not registered in the public land mobile network. In layman’s terms, the network provider doesn’t know who you or the recipient are.

Thankfully, there are a few solutions to fixing the problem. In a nutshell, the 5 fixes to this problem are:

  1. Check the phone number is correct
  2. Check your data allowance
  3. Perform a soft reset
  4. Replace your SIM card
  5. Contact customer support (if all else has failed)

Here are five quick and easy solutions allowing you to send texts again.

Fix # 1: Check the phone number is correct

The first and most obvious step is to ensure that you are entering the number it’s being sent to correctly.

If the number is correct, you can try entering the number with a ‘+‘ before the phone number.

If you are attempting to text a five-digit number or send a message to a reverse charge number, Vodafone has a restriction on this to prevent you from acquiring unexpected charges.

Make sure to check your online account and locate the ‘spend manager’ section where you will be able to enable/disable the service.

Fix # 2: Check your data allowance 

Occasionally an error 28 message can occur when you have exceeded your data allowance. If you are on a pay-as-you-go SIM then ensure you have sufficient funds by checking your online account balance.

If you are on a monthly plan, then make sure you have sufficient texts remaining in your bundle.

Fix # 3: Perform a soft reset

Performing a soft reset is sometimes a quick and easy method of fixing the Vodafone error 28 message.

To perform a soft reset on an iPhone, simply hold down the sleep/wake button and the home button simultaneously. Once an Apple logo appears then release both of the buttons.

On newer iPhones, press and quickly release the Volume up button, press and quickly release the volume down button. Then, press and hold the side button until you see the Apple logo appear.

Fix # 4: Replace your SIM card

Firstly, you want to check that your existing SIM card is inserted correctly. You could even try removing the SIM card, restarting the device, reinserting the SIM card, and then testing the messaging service again.

If you are still receiving error 28 and you have exhausted all other options then we suggest ordering a replacement SIM card.

Fix # 5 Contact customer support

If you’ve tried the above steps and are still receiving a Vodafone error 28 message then the final solution is to contact Vodafone customer support
