IMPORTANT: you must run the eduroam configuration app before installing software updates.

If you accidentally installed software updates, particularly the Android update to 5.0.2, access to stored secrets (e.g. SSO password) doesn't work. You can fix that by once more setting an access code (pattern, PIN or password) on your phone. See Screen lock for the details.

Configuring for data network

Before being able to access the 4G/3G data network, the proper settings have to be configured in the phone.

  • Open Settings (twice swipe down from the top of the screen).
  • Press the small gear button at the top.
  • Under Wireless & networks, select More.
  • Scroll to the bottom of the list and click on Internet settings.

After a while, connection to 3G/4G is possible and/or established.

If the phone's default language is French, the language can be changed as follows.

  • Open Settings (twice swipe down from the top of the screen).
  • Press the small gear button at the top.
  • Scroll down to Langue et saisie under Personnel.
  • Click Langue at the top of the list and select the preferred language.

Security and eduroam

Before configuring eduroam access, it is mandatory to set up a screen lock on the phone. Android requires the phone to be locked if you want to store secrets like your SSO password, which is needed for the eduroam setup.

Screen lock

Go to Settings (swipe down twice from the top of the screen) and select Security (under Personal). Choose first option Screen lock and set either a Pattern, PIN or Password.

Before setting up eduroam, you must have access to the Google Play store, either via 3G/4G or via a wifi connection (other than eduroam, for example at home). Furthermore, the phone must be secured with a pattern, PIN or password as described above.

In the Google Play store, search for nikhef eduroam and install the Nikhef eduroam helper app by Nikhef - Wilco Baan Hofman. You will need to execute this app once. It will ask for your SSO user name and password. Enter them and press 'Log on'. The app will generate a certificate, which will take a few seconds to complete. Afterward, you can access wifi via eduroam.

Email, contacts and calendar

This section describes how to configure access to Nikhef email, the shared and address contacts and the SOGo calendar. Please note that there are many different apps for email, calendar and contacts, so the configuration of your preferred apps may be different.


  • Open the Email app.
  • Goto Setting in the upper right corner.
  • Select Settings in the menu.
  • Press 'ADD ACCOUNT' in the upper right corner.
  • Enter your Nikhef email address and (SSO) password.

When checking the server settings, make sure the following are used:

port: 993
connection security: SSL/TLS

and for the outgoing mail:

port: 465
connection security: SSL/TLS

You should now be able to read and send mail!


It is recommended to configure the Shared Address Book from Nikhef.

First, you will need to install the app to connect to Nikhef's online address book. Go to the Google Play store and search for the app CardDav-Sync free by Marten Gajda. Install this app.

Subsequently, configure one or more address books.

  • In the Settings menu, select Accounts under Personal.
  • Choose Add Account.
  • Select CardDav.
  • And once more CardDav.

For the account:

server name:
username: your SSO username
password: your SSO password

and select Next.

Then choose your address book (e.g. Shared Address Book) and press the Finish button.

Optionally, repeat the above for the Personal Address Book and Collected Addresses.


If you want to connect to the calendar provided via the SOGo webmail, you need to install an app. There are two options:

  • The paid app CalDAV-Sync by Marten Gajda (EUR 2.59, to be paid via credit card, PayPal or Google gift card).
  • The free appp SolCalendar by SolStudio at Daum Kakao. This app provides a calendar and a CalDAV connector. It is possible to use the connector with other calendar apps.

Both apps are present in the Google Play store. After installation, these apps need to be configured. From your preferred calendar app, you can to select from the list of available calendars to which you want to connect.


  • In the Settings menu, select Accounts under Personal.
  • Choose Add Account, CalDav and once more CalDav.

For the account:

server name:
username: your SSO username (without
password: your SSO password

and select Next.

(Note: this is similar to the configuration of a CardDav account. Please see section Contacts for the screen shots)


  • To configure the connection via CalDAV to the SOGo calendar, start the SolCalendar app.
  • Press the settings button in the upper left corner. A frame with weather info opens.
  • Press the gear button in the upper right corner.
  • Select Synced accounts.

  • Press the + button in the upper right corner.
  • Choose Manual entry.
  • Fill in the connection details and press OK:
ID: your SSO username (without
Password: your SSO password

The connection is added and available to SolCalendar and other calendar apps.

Migrating data

To migrate data from one phone to another, there are two distinct scenarios:

  • You're using a cloud storage service like Dropbox, Google Drive that automatically synchronizes data from the phone to the cloud.
  • You do not use a cloud storage service and do not want to use one.

Both scenarios are described below.

For the Sony Xperia Z3, this tool can help to migrate data. Please note that it requires access to a computer running Windows or a Mac.

Independent of the applicable scenario, bear in mind that everyone uses different apps and each app has its own (in)flexibility concerning the location where data are stored. It is therefore not possible to give an exact description of which data and locations are relevant in your case. Carefully review the information present on the new phone before handing in the new phone (or resetting it to factory defaults, which will erase all data on the phone).

Migrating data via cloud storage

This is the easy case. Make sure that you configure the cloud storage on the new phone and all data should be accessible.

Of course it is possible that some apps refuse to use the cloud storage; in this case try the alternative scenario.

Migrating data without cloud storage

Migrating data without cloud storage is the more complex scenario. It requires copying the relevant data using a file manager, for example with Windows Explorer. (The complication is to identify which files and directories are relevant; see below for some hints.)

Via a USB cable

Connect the old mobile phone to a computer with a USB cable. Use a file manager on the computer to copy the relevant files and directories to the computer. Write down from which directories you copy these files; you'll need it later on the new phone. Make sure the phone device is detached (e.g. from the file manager) before disconnecting the USB cable!

Connect the new mobile phone to the computer whit a USB cable. Use the file manager to copy the same files and directories from the computer to the new phone to the written down directory/directories. Again, detach the phone device before disconnecting the USB cable.

Via a micro SD card

Place a micro SD card in the old telephone. Use the file manager app on this phone to copy the relevant files and directories to the new micro SD card. Write down from which directories you copy these files; you'll need it later on the new phone. Remove the micro SD card and put it into the new phone.

On the new phone, use the file manager app to copy the files and directories to the stored directory/directories.

Which data to migrate


Assuming that the old phone used the (recommended) IMAP protocol to connect to the mail server, there is no need to migrate email. Just configure the IMAP server as described above and you have access to all emails.


If you kept your addresses in your personal address book on SOGo or Google, then you don't need to migrate these data.

However, if data are local on the old phone device or its SIM card, the data need to be migrated. The easiest option is to export the contacts to Google or SOGo. Alternatively, you can export to a file and either copy the file via USB to the computer or place it on a micro SD (see above). Note: if you've configured Nikhef's Shared address book, the export will comprise all contacts from this address book. This will result in duplicate entries on the new phone.

It is recommended not to store contacts local on the new device or on the SIM card to prevent future migration trouble. Instead, use SOGo or Google instead.


If you connected the old phone to the SOGo calendar (or Google calendar) to register all events, then it is not needed to migrate calendar data.

However, if your calendar was local to the device, it needs to be exported. Please check the manual for your calendar app how to export a local calendar.


Check the following (not necessarily complete) list for other data to migrate:

  • Documents (text, spreadsheet, pdf)
  • Multimedia: music, photos, videos
  • Notes
  • Chats (WhatsApp etc.)
  • Downloaded files
  • Games etc.
