The cost of your Internet service will vary based on the type of provider, the speed of your connection, and your data access limits. Dial-up services tend to be the least expensive (often available for under $10 per month), but also offer the slowest performance. DSL and cable packages can range from as low as $15 a month for their lowest speeds, to $50 or even $100 a month for their highest speeds. Satellite and mobile providers commonly offer data packages, which increase in price for additional data usage. Some mobile plans offer unlimited data (usually for somewhere between $40 and $60 a month per phone), but many of them reduce your download speeds after you have used a certain amount.
