Wiki Prepaid Data SIM Card



Two wireless technologies are used to provide mobile users with access to the internet. We will concentrate on the mobile internet provided by cell phone network operators for most of this WIKI. There is an alternative way to get online, though: via WiFi technology. This page will focus primarily on getting access to public or commercially-available WiFi hotspots. Wi-Fi can be used to access portable hotspots. However, this mechanism is covered in detail on a separate page.

Wi-Fi is incorrectly spelled Wi-Fi or Wi-Fi but is often used as a synonym of a WLAN (or wireless area network) in certain countries. It is a trademark of Wi-Fi alliance.

It is a wireless technology that allows electronic devices to connect to the Internet using 2.4GHz and 5GHz frequencies. Wi-Fi technology can be used to give internet access to devices within range of a wireless network connected to the Internet. This access point is also known as wireless hotspot. The coverage area can be as small as one room, with walls that block radio waves or as large as several kilometres.

We won’t go into detail about technical specifications here, but we will examine which technology is best suited for travellers’ needs and where they can access it.


Many times, public Wi-Fi hotspots can be found free of charge at airports, airline lounges and hotels. Local governments offer Wi-Fi at no cost to use in public parks and government buildings.

Independent/Third-Party Subscription schemes

Rolling subscriptions are offered by some providers that allow users to connect to select public hotspots without the need to create separate accounts. Providers do not own the hotspots, but instead work with other Wi-Fi hotspot service providers worldwide. It may be possible to access a protocol that automatically connects to hotspots securely, depending on which scheme you have taken. If you do not intend to use them, these are non-exclusive and can be cancelled before the next subscription cycle begins. These schemes are priced according to the location, type/s of devices and the number of devices (e.g. Access on a tablet or mobile phone is cheaper than plans that offer access to a laptop. The subscription period length (e.g. Annual rates are more affordable than 12 monthly rates.

  • Boingo offers hourly, daily and monthly plans, along with different regional programs. Boingo also offers Passpoint, which automatically connects to a hotspot partner and securely does not require you to enter a password.
  • The iPass scheme is only available to business customers, and not consumers. If you are required to travel frequently for work, it is worth talking to your employer about this option.

You may also be able to access similar services through your credit card subscription, mobile provider, or home internet provider. This means that you don’t have to pay an extra fee. You may also be able to connect to eduroam from other educational institutions if you are a student, staff member, or faculty member of an educational institution that uses this network. However, you will need to register again in order to use it in another institution. eduroam can also be found in airports and public libraries. Although eduroam WiFi access is usually available for smartphones, it’s worth checking with your institution to see if it applies to you.

Mobile Internet vs. Wi Fi

Comparison: Mobile internet and Wi-Fi

Both technologies are technical in nature and neither is better or worse. However, each technology has its own advantages and disadvantages. Simply put, Wi-Fi works best if you’re stationary and mobile internet works well if your on-the-go. This is a big mistake. Wi-Fi can be used in trains and buses, but mobile internet can be used if you are at your destination.

Wi-Fi: The Advantages

Wi-Fi is great, and should be your first choice when it’s cheap or free. Wi-Fi can be found in many places (see the availability section). Log on, get online and consume as much data as possible.

Wi-Fi is often free and can be used for a long time, unlike most mobile internet plans. This gives you the time and data volume you need to download large files and updates that you wouldn’t be able to get with mobile internet. Streaming video, especially HD- or 4K-quality videos, is not recommended when you have unlimited Wi-Fi. A Wi-Fi hotspot for laptops is also a great option for devices you normally tether to your smartphone, such as laptops. This will save you any data that might be lost due to tethering.

Wi-Fi also has a wider reach than mobile internet. Crossing oceans to America can lead to frequency incompatibilities with non-American GSM phones. If you are unable to connect due to this, you can still access the free Wi-Fi available at McDonalds or Starbucks.

The Disadvantages Of Wi-Fi

The access point is stationary, and that is the main problem with Wi-Fi. It’s not a smart idea to spend the night in the lobby or corridor of your hotel. However, it can be a difficult reality for those who need Wi-Fi.

Although WIFI-FI is fast, it may not be as fast as the technology it uses to connect to the internet. This can be either a fibre- or landline ADSL-based technology. However, it may also provide slower access. Wi-Fi speeds decrease when more devices are connected to the same Wi Fi hotspot simultaneously. The provider may offer free public Wi-Fi access, which is often slower than the internet service providers offer to their business or home customers. However, in some cases they may offer a paid option that allows for faster browsing. Access to certain apps or websites (e.g. Youtube, Netflix) could be blocked in certain areas where bandwidth is restricted (e.g. Public vehicles

While most Wi-Fi providers offer unlimited data, some may have a fair use policy similar to mobile providers. Wi-Fi providers can reduce your internet speed if you use more data than allowed.

Wi-Fis that are “open” (meaning that access is not secured by password or registration) are considered very dangerous because anyone can view and access your data stream. These access points are not secure and you should not send any sensitive information, such as online banking or classified material. Your data is better protected by mobile internet. You can also subscribe to a VPN service, which specializes in providing secure internet access. Once you have logged on, don’t forget to log off before you visit other websites and apps.

You may need to register for some W-iFi hotspots and provide certain data, including your email address. You may need to create different usernames or passwords, which can be hard to remember. You may get many emails from the sponsor of Wi-Fi hotspots (although you might have an opt-out option).

Access protection by WPA2 security standard has become a common feature on Wi-Fis. It makes it slightly safer. To join, you will need the access code from the operator first. Some countries have closed WiFi networks for safety reasons. To log in to the Wi-Fi, you will need to register and obtain a password. To receive the verification code via SMS, you will need to have an active mobile signal. You can’t always depend on free Wi-Fi access points being available to you internationally.

Users of smart TV boxes/sticks may not be able to use public Wi-Fi connections that have a registration window, or even an “accept terms and conditions” window. Amazon Fire, Roku Chromecast, Apple TV, Roku. It may be a better idea to tether your smart phone to these smart TV boxes, if you have the data allowance.

You may find content that is normally only available to those connected to the internet in your home country if you use your phone’s data roaming function. This could mean that content normally restricted to Wi-Fi networks in your home country may be available to you once you have connected to the Wi-Fi network. Connecting to Wi-Fi could also result in you losing access to the app of your mobile provider, as they only work on 3G/4G.


Wi-Fi had some advantages over mobile internet in the past. With advances in mobile internet technology (e.g. These advantages are decreasing with the introduction of 4G, 5G and an increase in mobile data allowances offered by telcos.

Both technologies have their advantages and disadvantages, but you can use them all if you have both. If one of the technologies fails, you will always have a backup. This happens quite often. Mobile internet and Wi-Fi do not always have to be in competition. They can complement each other to provide a better internet connection.

It is difficult to predict your data needs, which you will need to do in order to purchase the right data package for your destination. If you don’t have a good knowledge of the area, it is nearly impossible to predict how much data you will use on mobile internet. This isn’t a problem with Wi-Fi, since you are rarely charged any fees. Mobile internet can be frustrating. You might spend a lot on a pack that you don’t use, but then you suddenly get free Wi-Fi. You should choose flexible or adjustable packages over inflexible ones. Start with a smaller one and increase later. wifi sim cards
