Welcome to Vodafone Community
Can't understand why I can't use my bundle data for hotspot purposes... Really what is the difference what I use my data on. As a new customer that only joined this week I think it's a joke. I've been with other network providers and never had this problem....
If you want to tether you need to use the correct APN. It should be:
If you use any other APN you may be charged. I recommend deleting all APN's except the Live one and the MMS one. Please note some phones cannot do this. This is outlined in the T&C's:
The XX data allowance can be used to access the internet via the below Access Point Networks only: Wap.vodafone.ie & Live.vodafone.com. Tethering over the HS APN or any other use of the HS APN will incur OOB charges.
If you're being charged for using the HS APN, it's definitely still active in the handset settings (if it wasn't there, it would either default back to Live, or not work at all).
Could you confirm if the firmware is a Vodafone Ireland release?
