I know someone who did and it worked for a while until the provider contacted them to ask about the unusually high activity. They explained the situation, but since their package was a B2C package and they were using it for their company, the provider told them to either stop doing it or switch to a B2B package. There was no unlimited text B2B package available at the time and all of them were quite a bit more expensive than B2C. The latter has changed since, but I'm not sure about the rest.
