Roaming - issues setting up Android
Hello Smarty community,
I am currently in Cambodia and my main phone decided to kick the bucket. I had a Smarty SIM in it. I've got a backup device with me (both phones purchased in the UK) so popped the SIM in, and I started the process of swapping over all my apps onto the backup phone. However I am finding that I can't receive OTP SMS messages to finish setting up my Whatsapp / Banking apps which is proving to be a major pain in the....
My first device happily received incoming UK text messages here after I followed the Roaming setup instructions from the tutorial on SMARTY website. I carried out the same steps on my backup phone but no bueno. I have a 3rd phone (US origin, SIM-unlocked) and this one won't receive UK text messages either, despite the Access Point Name setup.
Do I need a roaming addon to passively receive texts? I've never had one before and I received OTPs on my now dead Pixel 4XL. I've done it for Amazon account recovery and some .gov verification codes just fine a couple of months ago.
I am attaching a screenshot of my Access Point Name config for troubleshooting. If anyone manages to solve this - you'd be an absolute lifesaver, since these text message OTPs are holding me hostage from resuming normal operations with banking apps on the new phone.

Hi seb11 Yes, you will need a roaming add on in Cambodia, but data will cost £1.00 per MB.
Make sure that roaming is also enabled in the settings of the phone you are now using.
If the phone you are now using has eSIM capability, I would suggest an eSIM provider like Sparks or Airalo to get data up and running.
The Smarty price list for Cambodia and other useful info is here :

Let me try get an odd-on and see if I can receive a text message from the UK. This is literally the only scenario I need to make happen - for my day-to-day data needs I've got a local Cambodian SIM. It's just these pesky OTP messages for a few key apps registered on my SMARTY number . The strange thing is - I'm positive I never bought a roaming add-on before, and I received texts sent from the UK while abroad here (or perhaps I simply forgot!) I'll get back with the results.
EDIT
I bought a £5 out-of-plan addon and I'm still getting 'No Service - Emergency calls only' and zero bars on the network interface 😞 I tried turning Airplane mode on/off to give it a chance to reconnect - still no results.

That is most likely down to the network coverage in Cambodia - Try manually selecting a network rather than letting your phone automatically select a network - Your phone could be latching on to a signal from a network with which Smarty doesn’t have a roaming agreement. EDIT - Just read you are getting zero bars of coverage.
What is your back up phone ? Just wondering if it’s an old 2G feature phone, that may not be helping.
