If you want to live there long term, yes, but if you have years to do that then learning how to read won't be a problem. Many people manage to live in many countries being almost completely illiterate beyond an extremely basic level. For the internet you still have translate for the short term. It's not the same with understanding the spoken language because that's almost always a far greater obstacle. I'm saying that because learning how to speak chinese is generally considered far easier than learning how to read and write chinese.
