I am not 100% sure about Exonhost. I’ve found their service good, but thats it. Not excellent.
I’ll recommend exonhost if and only if you have no way to pay for an international hosting provider. In that case, you can get hosting from Exonhost. You can pay via bKash, Nagad or any bank as it’s a Bangladeshi hosting company.
Again, let me clarify. I’ll absolutely recommend to get hosting from Namecheap or WPX Hosting if you have the ability to pay for international services. If you don’t, among the Bangladeshi hosting companies, I’ll recommend Exonhost for now.
