At COSMOTE, we work every day to improve our mobile network, developing the 4G network even further.
Because COSMOTE 4G provides the fastest and most consistent and reliable mobile internet for all of today’s needs, we have no choice but to make way for its growth by discontinuing the 3G network.
This enables us to use the corresponding bandwidth to enhance the 4G network, which much more effectively meets our needs for faster speeds and reduced latency.

3G network removal
Would you like to learn more? You’ll find the answers to your questions here.
What is the 3G network and why is it being removed?
For more than 25 years the mobile telephony network has been growing at a fast pace, providing impressive services to consumers wherever they are. The 3G network dominated the 2000s, providing internet access for simple uses, such as sending pictures and e-mails, and surfing the web.

In recent years mobile telephone internet use has increased rapidly. In order to be able to support the constantly increasing demand for data, we are investing in 4G and new technologies such as 5G, and we are freeing up the spectrum used by the 3G network, in order to achieve the best possible online experience and to support the development of new services.
When will the 3G network be completely removed? What does 3G removal mean for me?
The gradual deactivation of 3G will begin in September 2021 with the target of it being completed by the end of 2021, when 3G coverage will be completely replaced by COSMOTE 4G. This means that:
  1. If you have a 4G device you will not be affected by the change, unless it is an older technology device, in which case you might observe some small differences.
  2. If you have a 3G device and would like an equally good or even better mobile internet experience, you will have to replace it with a new 4G device. Otherwise, you can continue to use voice and text services via the 2G network, albeit with less mobile internet capabilities.
  3. If you have a 2G device and you are satisfied with your mobile internet connection, you don’t need to make any changes.
How can I get the best mobile internet experience on the COSMOTE network
To get the best possible mobile internet experience on your network, we recommend you get one of the latest 4GVoLTE devices, because:
  1. Your experience will significantly improve, since COSMOTE’s 4G/4G+ network will provide speeds that are 6 times higher than the 3G network.
  2. You can also upgrade your voice service experience and via WiFi Calling coverage at locations where there is not enough mobile telephony reception (e.g. basements).
  3. You can use voice and internet functions at the same time.
Will there be any change in charges?
The removal of the 3G network will cause no changes to your monthly charges.
Is there a chance that I won't get 4G coverage?
We have developed the largest 4G network in Greece. All 3G coverage will be fully replaced by 4G. Furthermore, the free WiFi Calling service, which is available for all 4G VoLTE devices, will ensure coverage in the most demanding of locations (basements etc.) via WiFi, as long as there is a stable internet connection.
Will the 3G network removal affect my 2G device?
It will not affect it at all. Voice and text services, and the use of POS and other corresponding services for businesses will remain as is.
Will the 3G network removal affect my 3G device?
Following the removal of the 3G network, 3G device users will find they have very poor data services when not connected to WiFi. This will make it harder to follow social networks or use internet services in general. However, there will be no change to voice services.

For that reason, if you want to use mobile internet on your mobile phone, we recommend you replace your 3G device with a new 4G VoLTE device.
Will the 4G network removal affect my 3G device?
4G devices belong to one of two major categories:
  1. 4G VoLTE devices that support WiFi Calling services, namely, high quality voice services via 4G and calls via WiFi internet in areas with no mobile telephony coverage which, however, have WiFi internet access.
  2. 4G non-VoLTE devices that do not support WiFi Calling services.
This means that if your device is 4G non-VoLTE, there will be no difference to your internet service, except during your telephone calls.

If you want to upgrade your voice service to the best available quality and/or use of the free WiFi Calling service in places with inadequate mobile telephony reception (e.g. basements), we recommend you replace your 4G non-VoLTE device with a 4G VoLTE device.
Are 4G VoLTE devices expensive?
No. There are now very cheap devices on the market. Furthermore, with the Buy Back programme, we can buy back your old device and provide you with a new 4G VoLTE device at an even lower price.
Where can I buy a 4G VoLTE device?
We recommend you buy your device from a COSMOTE or GERMANOS store or from our website. This will guarantee that you are 100% certain that your device will operate in the best possible way.

The device can, however, be purchased at any other physical of electronic point of sale in Greece, with confirmation from the store regarding the sound operation of the WiFi Calling service.
I have a tablet with an incorporated SIM card. Does the 3G network rmoval concern me?
If you have a 4G tablet you don’t need to do anything. If you have a 3G tablet, you will have to replace it with a 4G tablet in order to go online when you are not connected via WiFi.
I have special pocket WiFi (or USB stick) equipment for internet access. Does the 3G network removal concern me?
If you bought specialised equipment more than 5 years ago, it is very probable that you will need to change it in order to continue going online.
I am a subscriber of the COSMOTE Double Play SIM service. Does the 3G Network shut down affect my Service?
  • If you have the HUAWEI B315s-22 device, you will need to replace it in order to continue to have voice and Internet services from COSMOTE Double Play SIM. The device will be replaced FREE of charge by COSMOTE and all you need to do is to visit the nearest COSMOTE store to pick it up. It is also needed a SIM card replacement that will also be for Free of charge from COSMOTE.

Then all you need to do is plug in your new device and enjoy the COSMOTE Double Play SIM service, through the 4G / 4G + network.

  • Then all you need to do is plug in your new device and enjoy the COSMOTE Double Play SIM service, through the 4G / 4G + network.
How can I find out what type of device I have?
Visit one of our COSMOTE or GERMANOS stores, show us your device, and we will tell you. You can also call 13888 or visit our website, where you can find all the 4G VoLTE devices that support the service.
Is it enough to buy a 4G VoLTE device to get the WiFi Calling service?
No. Right now you will have to activate the relevant service. To do this, send a free text message with the word “WIFICALL” to 1333.
I travel abroad often, will my international roaming use be affected by the 3G removal?
The removal of the 3G network only concerns use in Greece. Abroad you can also use your device on 3G networks, although we always ensure you get 4G speeds so you can enjoy the best user experience even when abroad.
I use th COSMOTE plans for the operation of IoT applications via specialised devices. Will the 3G network removal affect me?
If your devices are compatible with 2G technology and your application speed requirements are covered, you will not be impacted.

In all cases, we recommend you gradually transition to 4G/4G+ IoT solutions for even better speeds or NB-IoT for better power efficiency and good reception, even in conditions with bad coverage.
