I was with Smarty for 1 year and 7 months. At the time they were the cheapest option I found and I was also interested in getting money back for unused data. They are no longer the cheapest option and a couple of problems I had with them recently led to the decision of leaving them. The did nothing to solve the issues, they just waited for me to leave. For everyone's sake, I will only share here the second incident. Out of the blue, my phone lost the ability to send or receive messages from/to outside the Smarty network.Calls and Data were fine. I could also send messages to my wife (also on Smarty), but messages to other people would never be received. I actually found out about this issue because due to my work I constantly need to receive text messages and I started receiving fewer than usual. Then I tested further and realised that it was anyone outside Smarty. They have an email address but it takes days to get any answer. When there's an incident, this is not an option. They have no phone number to call, so the only option is a web chat. It's the same experience as a call centre. You speak to several people that know nothing and maybe after 1h chatting, you find someone who actually cares.I had several chats, all the same. They asked me again and again to reboot my phone and similar nonsense. Finally, I thought I'd made some progress when they said that there was an incident in the area with the Three network. I could actually check myself the status of the incident on Three's website. When the message was cleared from the website my line was still not working properly and I contacted them again, only to be asked again to reboot my phone, etc. They did nothing until I threatened to leave. Then, all of a sudden, they offered to escalate this to the "network team". I don't know if such a team exists or if they can solve any issue, but after 4 days they fixed nothing and not even bothered updating me.When i contacted them again, they told me that the network team had concluded it was my fault. According to them, they had looked into the issue and seen that my phone was not communicating with the tower or their network.It's really funny considering that I could send messages to Smarty just fine, plus calls to anyone and data was also fine.It's also funny considering that at some point they decided it was my fault but didn't really bother telling me. This looks to me like they didn't even try and just waited for me to call back and tell me some more nonsense. They did nothing else, not even offered replacing my SIM card.In the end, I moved my number to another company and guess what... I put the new SIM card in and everything started working just fine with my "broken" phone. Smarty, you are very unprofessional and have no idea what you are doing. You wasted my time and just waited for me to go away. So, I respected your wishes and moved my 4 lines to another company. I only had issues with 1, but after seeing what really happens when there is an issue, I didn't want to risk it.
