How the eSIM/SIM works – What is this eSIM/SIM & How it works

1.The Geokall Mobile™ eSIM/SIM is Global.
2. The SIM uses the Global System of Mobile Communication (GSM) technology and can connect to 3G, 4G and 5G networks (the latter if the roaming network supports 5G and if your device is a 5G Phone or Tablet).
3a. The eSIM is installed via the eSIM QR Code or via the eSIM Activation Code in an eSIM Supported Device (Smartphone, Tablet and Wearables).
3b. The physical SIM is inserted into an unlocked GSM phone. The SIM is compatible with 99% of most unlocked GSM phones in the market including the Apple iPhone and tablets such as iPad, Google Pixels, Samsung Smartphones, etc.
4. An unlocked GSM phone has a compartment for a SIM, and you insert the SIM into that compartment.
5. The Geokall Mobile™ SIM Card is a Triple Punch SIM Card – which means, depending on the SIM Compartment of your phone whether it is for a Mini, Micro & Nano SIM, you can either break off the Mini SIM, Micro SIM, or Nano SIM from the SIM Card for your phone. At the back of the Geokall Mobile™ SIM you will see faint lines from where you could punch to break off the Mini SIM, Micro SIM, or Nano SIM from the SIM Card.
6. The Geokall Mobile™ eSIM eSIM or SIM could be mapped to Phone Numbers available in 60+ countries. Ideally the Geokall Mobile™ eSIM or SIM could have more than 2 phone numbers from two different countries and could be used interchangeably by switching to make one a default Caller ID and vice versa.
7. You can program your outgoing caller ID of the SIM to be either the US phone number, the UK phone number, Canada phone number, Australia phone number, Germany phone number, Brazil phone number, etc. and use from wherever you are you are in the world. It does not matter the country you are in with eSIM or SIM. Instructions on how to program your Outgoing Caller ID are contained in the Operational Manual. Click here to download this manual.
8. The eSIM/SIM works in 200+ countries on 850+ networks worldwide to place and receive calls worldwide, including the USA, Canada, Mexico, United Kingdom, Ireland, Brazil, Venezuela, Costa Rica, Australia, New Zealand, Germany, Ireland, France, Italy, Spain, Austria, Hungary, Switzerland, Belgium, Russia, Ukraine, Nigeria, South Africa, Egypt, Kenya, Ghana, Niger, Sudan, United Arab Emirates, Saudi Arabia, Israel, Palestine, Lebanon, Oman, Kuwait, Bahrain, Turkey, Cyprus, Jordan, Malaysia, Indonesia, Hong Kong, China, Japan, Thailand, Vietnam, Afghanistan, Kazakhstan, and many more.
9. The eSIM/SIM is programmed as a Global Roaming SIM with cheap outgoing calls and free incoming calls than most local networks. It is cheaper and better than using a local telephone network in your country to travel abroad and roam with it because those networks are not actually programmed for affordable international telephone calls when roaming abroad. The Geokall Mobile™ does provide such cheap calls.
10. The Geokall Mobile™ eSIM/SIM makes and receives calls with the SIM known as SIM initiated call; makes call through the Web (known as Web initiated call) but actually answers and talk with the phone), that is, the user initiates a call on his/her Geokall Mobile™ account online using any device [phone, laptop, computer, iPad, iPhone] that has an internet connection and then pick up the call to talk using a phone, any phone with a network including the Geokall Mobile™ eSIM/SIM. The Geokall Mobile™ eSIM/SIM also sends and receives SMS (Short Message Service) worldwide; the SIM also can be used to access the internet: browse, send and receive email as long as the phone or device the SIM is inserted into has web browsing feature/s.
11. The Geokall Mobile™ customer after receiving the SIM Card, breaks it off from the Card that holds the SIM and then insert it into an unlocked GSM phone and then the SIM will pick up a network in the country the SIM is physically located, then within few seconds, the customer will receive a notification via SMS of your Geokall Mobile™ UK Telephone Number.
12. The Geokall Mobile™ eSIM/SIM user can then place [if he has credit in his account] and receive Free Incoming calls in that country on the UK number if that country is one of the Free Incoming Call Countries.
13. The Geokall Mobile™ eSIM/SIM user have full access 24/7 to his/her account online via the eSIM/SIM Account Self-Care Portal to manage his calls, see call history, reload airtime, set preferences such as voice mail for his/her SIM and see download call logs on real time basis for the SIM and could subscribe for data bundles and mixed subscription plans.
14. You are to ensure that you use your Geokall Mobile™ eSIM/SIM to place or receive a call even for few seconds or a minute or send or receive an SMS at least for once within every 12 calendar months to keep your eSIM/SIM active if you do not intend to be using the SIM frequently or regularly. If your eSIM/SIM does not do any activity mentioned above for up to 12 calendar months, it is apparently you will lose it or let us know your reason/s that you may not be able to use your eSIM/SIM for a period of up to 12 calendar months after it is activated or after you receive your new eSIM/SIM from us without activating it, whichever may come first. Your eSIM/SIM is said to be activated once you insert it into a mobile phone and it automatically.
15. The SIM saves you over 90% of telephone costs when traveling abroad because you do not pay any roaming charges, no monthly bill, no pre-departure travel obligation, no maximum use policy, no hassle, and no story.
16. The Geokall Mobile™ eSIM/SIM has low outgoing call rates; from 3 cents per minute call in some countries to 6 cents per minute call and above in other. There are many other features such as call forwarding, Voicemail settings, etc.
17. For instance, if you travel 5 times or more than that in a year with the Geokall Mobile™ eSIM/SIM where your total telephone cost/bill is between $135+ in a year compared to other local networks in your country where if you use any of them to roam abroad for 5 times or more in a year, you will be spending between $2500 and $3450. Some customers of Geokall Mobile™ who were using those local networks to roam abroad and who are now using the Geokall Mobile™ said some networks even billed more than $5000 in three trips overseas without thorough explanations. This does not include the monthly plan they may be billing you if your phone is on a monthly plan per say, which ranges from $25 to $190 (for those who are on higher plan which may allow calling home when on international trip). But with the Geokall Mobile™ eSIM/SIM, you will spend far less than and save more and have choices and with wide coverage and in turn have control over your spending, call monitoring, etc.
18. Imagine a world where you do not need to buy SIM card in each of the five countries you travel to or have more than 4 SIMs buying a SIM in each country you travel to just to place a call and receive call, but with the Geokall Mobile™ eSIM/SIM, you are okay with just that one Geokall Mobile™ eSIM/SIM: ONE eSIM/SIM for the World and ONE SIM for all your telecommunications and Internet access when traveling abroad! The Geokall Mobile™!!
While some may say they use Skype and other internet phones to place a call free of charge and you will need data from some other provider to power your Skype or WhatsApp,, yet you cannot compare this with the Geokall Mobile™ eSIM/SIM, which also have the Softphone utilizing the eSIM/SIM data at even cheaper rates than most Internet Phones in the United States such as Magic jack, Vonage, Rebtel and other Internet Phones’ providers from other parts of the world, of which these internet phone provider companies will need you to get data to power your internet phone before you could make and receive calls.
19. Imagine a mobile world where you do not need to inform your telephone network provider that you are traveling to so and so country for them to REALLY program your phone to work in those countries, which in some networks, cannot be more than 3 to 20 countries for you to place and receive a call and if you go beyond that, your phone will not work or you are billed a higher bill. But with the Geokall Mobile™ eSIM/SIM, you do not need to pre-inform us, and you are good to travel abroad with it at any time and any day.
