In case you are planning to use Clay Sim Cards for ny of your international travels, its a request please think not twice, but thrice!! I used a Clay sim card across Europe, cz they claimed they have the best network connectivity and everthing is smooth!! It was nthing but crap.. I could barely make calls, cz most of the time there was no reception on my phone, while my co-passengers had full signals!! Clay telecom is the worst option that one can ever find! Plus trust me even if you don’t use it, they will bill u..
