What is GSM?
GSM stands for Global System for Mobile communication, but the simple everyday meaning is that it is a phone that can easily roam between different networks. A phone that does not support GSM cannot connect to a network that it's not part of. Phones that do not support GSM technology are not suitable for use on trips abroad.
What is roaming between networks?
When you are abroad and your phone goes out of range of the network to which it is connected to, it connects to a different network. Doing this is called “roaming” from one cellular network to another. Roaming charges are the phone activity that have made on the network to which you roamed, air time tariffs, call setups, and connection and billing to your original network.
What frequencies GSM phones are using?
GSM phones use four different frequencies worldwide. GSM networks in North and South America operate at frequencies of 850 or 1900 MHz, while most networks in other countries operate at frequencies of 900 or 1800 MHz. Every country in the world has 3G services but Japan and South Korea operate only on 3G technology at 2100 MHz. We recommend 3G, 4G or quad band mobile phones for most international travelers. Since these wireless devices operate on all four of the international GSM frequencies, you ensure the broadest international coverage available. A "tri-band" phones that covers 900, 1800 and 1900 MHz might be enough for most countries. Please check the frequency at your destination country before you travel to make sure your phone supports it. The web site www.gsmworld.com/roaming/gsminfo/index.shtml
can provide you this information.
Why are roaming charges abroad so expensive?
When you use your phone abroad you are serviced by a network that "does not recognize" you. Since this network has no interest in keeping you as clients, or giving you discounts, they just treat you as tourist. Cellular operators abroad make billions of dollars from airtime from tourists like us. The idea of a local or international SIM card is to allow us not to pay exorbitant tourist tariffs, while also making dialing much easier.
A SIM (Subscriber Identity Module) card is a smart card that can store user information on a cellular phone, such as personal details, user settings, phone numbers, messages, textual information, and multimedia. A SIM card can send and receive settings and information from the network and the user phone. The SIM card is usually located in the back inner part of the cellular device, behind or near the battery, and can be taken out and replaced if the phone is not locked.
What is a "SIM lock", or a locked mobile phone?
A "SIM lock" is in essence locking the cellular device from roaming between networks. The reason that the cellular providers lock their devices is that users use only their network and won't roam to other providers and spend money with them. When the cellular device is "locked", the SIM card inside does not connect to different providers.
What is a local SIM card?
A local SIM card is a SIM card that belongs to a certain network in a specific country. For example, a local SIM card in Spain allows you to talk in Spain, and be charged local rates, as opposed to tourist rates (i.e. roaming charges). When you travel to a certain country and put in your device a local SIM card for that country, you are in affect forgoing your agreement with your local provider back home, and using the device to pay local rates.
What is an International SIM card?
International SIM card is SIM card that works in more than one country, sometimes over 180 countries. This SIM card works using the infrastructure of international companies, and allows you to roam with your SIM card between countries and take advantage of the local agreements between the carriers. Every international SIM card has more effective countries, along with countries that prefer not to allow coverage. The power of the international SIM card lies in two main advantages: Firstly, the providers of the card are able to procure good local rates with the partner carriers, such as free incoming calls, or low rate outgoing calls. Secondly, purchasing of this is suitable for people that are not interested in buying local SIM card in every country they go to, but rather to buy one card for all of Europe for example.
SIMCardGlobal.com has international SIM cards, which works in over 195 countries, over 45 of them with free or $0.05 and under on incoming calls, and huge savings abroad.
A dual SIM mobile phone is one which has two SIM. Dual-SIM adapters are available to allow cell phones to contain two SIMs, and to switch from one to the other as required. Some phones are designed to work with two SIMs, both of which may be active at the same time. Dual-SIM operation allows the use of two services without the need to carry two phones at the same time. For example, the same handset can be used for business and private use with separate numbers and bills; or for travel, with an additional SIM for the country visited.

How do I unlock the SIM lock?
In order to unlock the SIM lock or "SIM-Free" as it’s called by the cellular providers, you need to contact your cellular provider and ask for a SIM unlock. The provider is required to implement this unlock, consisting of entering a code, and may sometimes incur a fee. We do not recommend it
, but there are guides on the internet which tell you how to unlock the phone independently, without the services of the cellular provider. You can type the words "SIM Free" in a search engine, and some of the relevant results will instruct you in unlocking the phone. www.mobileunlocked.com
is one of the web sites that can provide you with this service. We acknowledge that in order to use a foreign SIM, there is no choice but for the cellular providers to unlock the phone.
How do I change a SIM in my mobile phone?
So you purchased a new SIM card, and flew abroad, now that you land what do you do? How do you make the change itself?
In general this is done according to the manufacturer's direction for the phone, but a rule of thumb states that: You turn off the device, change the card, and turn the device back on. The SIM card is usually located in the back part of the device behind the battery so that you need to power it down before you switch.

Normally, you do not need the PIN to operate the SIM with your phone.

I cannot make calls. Why?
There are several reasons why you cannot make calls. Most of them are initial setup issue. For troubleshooting please click on the Support tab at the top of the page and follow the instructions.
I have forgotten my website password. What do I do?
You can have your password emailed out to you by clicking on the Forgot Password link on the "My Account" login page.
I have forgotten my SimCardGlobal.com number. What do I do?
With Atlas +44 SIM card in your phone dial *133# and you will get SMS with your number. I lost my SIM card. Can I deactivate my SIM card?
Access your account and send E-mail to Support from the web site. Add identification information so we can identify you and deactivate your account.
How can I contact SimCardGlobal.com?
Click on "Contact Us" on our web site and fill the "Contact Form". We usually respond within 12-24 hours. You can also dial short code *154# on your mobile phone to talk to a customer service representative. This is a paid call with rates as a call to USA from the country you are in.
I am in France and cannot make outgoing calls
Make sure you are on SFR or Orange network, as the other networks are weak. If you are not on one if these two networks, switch to it manually. Find the network menu on your handset and search for networks. Once you see the list of networks, select either SFR or Orange.
I cannot find the SIM menu on my Samsung or HTC phone
Samsung and HTC phones are known to have compatibility issues. Some of these issues can be bypassed. For example, dialing a + before the number is not working, but you can dial * instead. In some Samsung phones you cannot switch your profile from the default "Global Roaming" to another profile. Sometimes, you cannot even see the SIM menu and get a message like "Invalid SIM". So, if the Profile menu does not pop up when you restart the phone and you can’t find the Profile menu on your phone, Dial #988<send>. If it gives you error message, ignore it and just click on <end>. This should pop up your Profile menu, so you can switch to the desired profile.
I can not find the SIM menu on my phone running Android operating system
On phones running Android operating system version 2.1 and above, you can find the SIM menu on the main menu and it called "SIM Tool Kit".
I am not getting data services
First, make sure you set up your cell phone or tablet correctly. To be able to use data services you need to setup the Data Connection on your mobile device. Define a new connection, give the new connection a name and set the APN field to globaldata. No need for username/password or any other parameters.
