A lucky find on web search
I found doctorSim by chance and we have used twice while in Morocco. Simple to use with varied choice of payments. They take security seriously and respond quickly to email.
If you need to top up a sim on the go, especially a foreign country sim then doctorSim is easy and quick.

I have ordered twice
I have ordered twice. Never got a penny credit to my phone. I did everything the site said to do to activate the amount. NOTHING!
Refunded money after the complaint was placed.It would be helpful if they had instructions on their site. I did everything they asked, but had to spend considerable time figuring it out. Even then, it didn't work.
My idea would be to pay, then get a credit to your phone.PERIOD.

Kinda skeptical about this.
Kinda skeptical about this.. app. I'm just trying to figure if my Samsung is truly carrier unlocked as it works on any carrier anyways but some things don't seem to be working fully. And in the email it was stated that I have an iPhone? I'm using a Samsung Galaxy S23 FE and even provided the IMEI number but you guys are calling it an iPhone?
