I gave my absolute best effort and gave WorldSIM many, many chances. I was by no means impatient with them or their products, but after all my months of effort, it's very obvious that this is a 1 star company or less. Starting with their website, which is very poorly made and definitely lacks vital instruction on how to properly setup and configure their SIM cards once you've purchased them. These are the steps I've gone through with this company (attached list of emails with many, many replies per thread):
* Visit their website for the first time, didn't gather enough information on the difference between a Data SIM card and International SIM card, so I utilized the website's built-in chat feature. While the representative that I got was clearly struggling with English, after pulling teeth I eventually learned that Data SIMs cannot (supposedly) accept phone calls or text messages. So I decided to get an International SIM for my phone and a Data SIM for my hotspot. Later I find out there's literally no difference functionally.
* Fast forward to I receive the SIM cards in the mail, I immediately go onto the web portal and try and "activate" the SIM cards by putting in their ID. Neither of them were able to be added to my account for a reason I still don't know. Contact customer support, pull more teeth, finally get them added
* They are now added, but do not have the 100 GBP I added to either of them. Contact support MULTIPLE times on this account throughout the week and finally receive my credit.
* Attempted to add a virtual number to my international SIM card: my card was charged for it, but there was an error saying it could not be added. Contact customer support AGAIN and they finally add the number for me.
* Was told to enter a special code into the PIN pad on my phone in order to activate the number that they added. No surprise... DOESN'T WORK. Contact customer support for the nth time. They said these exact words (photo provided): "As we can see due to some error you were getting an error. You can try to use the services now as the issue has been resolved."... Thank you I guess? It was fixed after this but seriously? It's now becoming very apparent I'll have to contact customer support for literally anything that needs to get done.
* Number actually does work after this for making calls, but apparently you cannot receive SMS which is a HUGE let down which is EXTREMELY obfuscated on their website.
* Try the same with the Data SIM card in my hotspot, NO SERVICE. Try in my phone, NO SERVICE. Try many different configurations, NOTHING. Guess what. Contact customer support, they say there's some special APN (?) configuration they need to do on their end. Still waiting to hear back about this.

WorldSIM, if you're reading this, make a product that actually WORKS so your customer service workers aren't constantly berated with requests to do things that the product claims to be self-service. To anyone else reading this, please spare yourself the time it takes to get these working properly and just choose another company. Sadly, I have no other company to refer you to, but I'll be trying some other global SIM card provider shortly. Customer support is the only thing that works at this company, which would be great if anything else worked.

I was buying an R4i Gold and payment was a bit unorthodox (send personal PayPal to an address specified via email) but ended up receiving the product merely days later. R4 also was exactly as described,
