Highly frustrsted

My husband and I are in India,he has almost no access to his phone. His name is Conrad Pillay and he is on ***,he has quite a few numbers with Vodacom but this is his main number. Before we came to India,he spoke to various agents about having his line open and operational,they advised he buy travel bundles,so he did that,they said one we here in India,switch on and of and it will work,well it did not. I don't understand why they didn't just open the line for international roaming....so we are so upset and highly frustrated as we were put in such difficult situations without his phone been open and operational.Literally a nightmare....we do have some access on our phones but only in the hotel via wifi....we needed full access while out and about....please help us resolve asap....its hard without a phone in a country we coming to for the first time....please contact my husband if possible or when he's back at the hotel after 5....thank you🙏🏻
