						Shellphone is your go-to app to use your phone number over the internet. It integrates

					<Accordion title="What do I need to use Shellphone?">
						Shellphone is still in its early stages and we&#39;re working hard to make it as easy-to-use as
						possible. Currently, you must have a Twilio account to set up your personal cloud phone with
						Shellphone.

					<Accordion title="Why would I use this over an eSIM?">
						Chances are you&#39;re currently using an eSIM-compatible device. eSIMs are a reasonable way of
						using a phone number internationally but they are still subject to some irky limitations. For
						example, you can only use an eSIM on one device at a time and you are still subject to
						exorbitant rates from your carrier.
