Hi @jea1301
Welcome to the Customer Helping Customer Community of Vodafone.
Do you have your roaming enabled on your phone (in your device settings)? For more foreign settings, such as APN setting, see this page: https://community.vodafone.nl/t5/Tips-van-Vodafone/Instellingen-mobiele-data-in-het-buitenland-roami...
If the above is not the problem, please switch off your device and then switch it on again. If this does not work, you can always try to put your device in airplane mode and then back again, and if that does not work, you can try to switch providers manually. If this is no longer possible, please contact Vodafone customer service. This can be done via the internet by starting a chat or by calling Vodafone (+31 654500100).
