No problem. You can upgrade instantly at any time and you simply pay the difference between the two plans.
You can downgrade the package just before it's renewal date.
The vast majority of web hosts use a cPanel feature called "addon domain" to allow unlimited websites per hosting account. The additional websites share the storage space, resources, and user name with the primary account. This means the allowed resources for each website will be very small and it won't take long before your website falls outside of the normal usage range. At that point you will be forced to buy a more expensive hosting solution.
In addition, you can't choose different data centers for each website for SEO purposes, get a dedicated IP, install SSL certificates, or get cPanel access for those additional websites. It becomes a complete mess if you decide to swap main and additional domains for any reason, or if you try to get separate cPanel access for a single domain. Also, remember, you only get one free domain registration and you will have to buy additional domain names.
Instead of offering an unlimited domains feature, we strive to keep our services as flexible as possible. This allows each hosted website enough resources to grow. 2MHost offers a very affordable $1 hosting plan, which is great for new websites.
At 2MHost, we appreciate your continued business. Most web hosts use a low introductory price to gain customers and dramatically increase the price for those who renew their service. We offer a LIFETIME Price Lock Guarantee. You get unlimited renewals at the price you sign up for today - guaranteed!
2MHost has been providing affordable web hosting services for over 14 years. In that time, we have found that 99.95% of hosted websites fall into the "normal" usage range.
Typically, websites that fall outside of the normal range are:
As a customer you can monitor your Disk usage, Bandwidth, CPU, and RAM usage within your cPanel.
Again, only 5 out of every 1000 websites exceed normal usage. We monitor our servers 24/7 to ensure optimal operating performance.
