I have a Finow X5 for 10 days.

I have a Finow X5 for 10 days. Yesterday I placed a SIM in it and I get many issues with the data connection which is totally unstable. Do you know how can I fix that? Anyone has the same problem? Than you

be sure your APN is set to the best one for your carrier.

have u tried restoring oem specs…and…btw…did u cut the simcard or have it done properly?
