Knowroaming Global SIM Sticker: SIM Error

Knowroaming Global Sim Stickers are great for travellers, simple to apply and use, you get a free UK number and a US one if you want, best of all the rates are really good. 

One down side to them though, they are single use, meaning once they are applied to your SIM card, that’s it, if you change network providers or get a new SIM card, you need a new knowroaming Global SIM sticker, which you will have to purchase. 

Recently I changed my network provider, so a new knowroaming Global SIM sticker was purchased, which took a couple of weeks to arrive, applying it to my SIM was still easy, and popping it into my iPhone went all good, but then problems. My SIM initially worked, provider was displayed and also 4G data symbol, then it displayed SIM Error, after some messing about with the phone settings I finally got it to work, here’s how;

  1. Either change Data to 3G or 2G and restart phone. 
  2. Activate and connect to WiFi.
  3. Navigate to settings, phone, SIM application.
  4. Scroll to the bottom and select “Check for Update”, it will take a few seconds, but it will display its progress (initially it looked like it wasn’t doing anything, but it was).
  5. When finished restart your phone. 
  6. Change your Data back to 4G. 

Everything now works great, with step 1, you may be able to just disable Data, rather than change the Data rate.

Digital Nomad Tech Gear: Nextstand Laptop Stand

Canon EOS M3 LCD Display Replacment & Repair

The Canon EOS M3 camera is a great tool, small, easy to use and with DSLR functions, with my only gripe being it has no view finer, meaning it solely relays on the digital touch screen LCD, unfortunatly mine argued with a rock wall and lost, cracking the screen. Luckily the display was still fully functional, although it had an obvious multiple cracks, I decided to apply a cut down iphone screen proctector, just to protect my fingers and hopefully prevent it from getting worse (yes, I know I should have put one on sooner!).

The challenge now was finding a new screen (user damage is not covered under warranty) and fitting it, so I began searching on the internet for any repair info, there was lots, but nothing for the EOS M3, Hense this post.
To remove the old screen:

  1. Remove the battery.
  2. Remove the 2 screws on the right side (where the controls are)
  3. Remove the 3 screws from the underside (same side as the display)
  4. Remove the screw from the top left.
  5. Flip the display out and over (exposing the back), now remove the 4 screws (2 top and 2 bottom by the hinge) on the back of the camera.
  6. Flip the display back in place.
  7. Slide off the rear housing (carefully) to expose the 2 ribbon cables.
  8. Unclip the ribbon cables: (A) for the control cable, the clip on the ribbon side flips up. (B) for the display the clip opposite the ribbon flips up. 
  9. Remove the 2 screws on the rear of the housing holding on the display.
  10. Carefully peal off the display ribbon from the case (its held on by double sided sticky tape).
  11. Now replacing the LCD is just the reversal of above.

Its a simple and straight forward operation to replace the LCD display assembly, finding the LCD display assembly was the challenge, as very few places sold them and the ones that did was expensive (over £100). I did manage to find one on ebay for £60.00 GBP + postage, however on arrival although being new, it didn’t work, so it was returned.

I am currently looking for another one and I will update this blog post with my findings.

PHPBB 3.x + PostFix + Virtualmin + Mass Email = FAIL

I have been using CentOS and Virtualmin for a number of years and recently I a requirement for a forum based system. I used PHPBB a number of years and so this was my first choice.


PHPBB installed correctly and i had the site up and running in no time, then one of the users complained they had requested a password reset, but never received one?

The core system was CentOS with the ‘full’ install of Virtualmin, before I have only used the webmin module for Virtualmin, so i started to debug the log files.

I tried sending an email in PHPBB using the ‘mass email’ function but the error was:

E-mail error
» EMAIL/PHP/mail()

There was no real obvious signs in the logs apart from:

postfix/sendmail[19438]: fatal: chdir /var/spool/postfix: Permission denied

In the ‘maillog’ log file.

I checked the PHP.INI config file and it was correct, for using Postfix

sendmail_path = /usr/sbin/sendmail -t –i

So it was head scratching time! I then remembered that in the past I have always had issues with SELinux and generally with internal servers i disable it. So i checked the settings and it was enabled, so i disabled it and rebooted.


Change SELINUX=enabled to SELINUX=disabled

Gave it a test by sending a test ‘mass email’ to a user and it worked, I then got the user to request a new password and that also worked!
