Make sure your broker will reinvest for free the dividends into shares of VOD. If broker won't- get one that does like TDAmeritrade. I may pay a bit more in commissions versus discounters like Scottrade but my platform and perks more than make up for it. It's an opportunity for you to share in both growth & profits without compromising your philosophy.
Unless something changed only a few US Banks/Brokers are able to reinvest VOD dividends since it's a foreign company. I know for a fact the Schwab can not reinvest dividends in VOD. BNY Mellon and Citibank brokerage services can reinvest dividends. Both have strict buying and selling rules as well as handling fees for the drip.
