How to pick the best prepaid phone carrier
4G LTE & 5G data speeds: Since all the best MVNOs operate on the big three cellular networks you'll pay less without sacrificing speed. More and more are adding 5G coverage all the time so you can expect high-speed data.
Unlimited talk and text messaging: Finding a new unlimited plan has never been easier. Virtually all small carriers include unlimited text and calling in their plan options.
International calls to Canada and Mexico: International calling is a must for many people. Luckily MVNOs offer international phone plans, with free calling to certain countries like Canada and Mexico, and discounted rates on others.
Bring your own phone: To save even more you can bring your own phone and just insert a new SIM card.
eSIM: Most carriers now support eSIM, which means you can switch immediately without having to wait for a SIM card to arrive in the mail.
Multiline discounts: Low-cost carriers also offer some of the cheapest family plans, with multi-line discounts.
Wi-Fi calling: This feature is handy when you're out of your service area, allowing you to make calls over the internet instead of on your cellular connection.
Tethering/hotspot data: Many low-cost carriers allow you to use your phone as a hotspot. Pick an MVNO with the best mobile hotspot plans so you can share your mobile hotspot data with other devices.
HD video streaming: Just like the big guys, some MVNOs offer HD video streaming and some don't. Read the fine print to find the option you want.

SIM card sizes
There are three different SIM card sizes in the various Apple iPhone models. Each has an adapter in case you want to switch to a phone with an incompatible SIM Card slot.
Standard SIM Card - The original SIM Card is similar to any card in your wallet. However, if you want to transfer your data to a new phone, you can take out a small portion of the SIM card to insert it into another iPhone. The original iPhone along with the older iPhone 3G and 3GS all use the original SIM Card, according to Apple.
Micro SIM Card - Micro SIM Cards were introduced with the iPhone 4 in 2010. The Micro SIM is also used in the iPhone 4s. The Micro SIM Card size is small compared to the original SIM card but not quite as small as the Nano SIM card.
Nano SIM Card - Nano SIM Cards are the smallest SIM cards that came out in the iPhone 5 in 2013. The cards have been in every iPhone since, all the way up to the iPhone 7 Plus.
How to remove a SIM card
To remove the SIM card from your Apple iPhone all you need is the SIM card remover tool provided to you when you bought your phone, or a small paper clip.
If using the paperclip, unfold it and gently insert the end into the small pinhole in the SIM tray.
Press gently until the SIM tray pops up, you do not need to use much pressure.
Pull the SIM tray out gently, be careful the SIM card does not fall out.
Swap your SIM card over, making sure you have aligned the SIM in the correct position.
Re-insert the SIM tray into the iPhone.
