CTCellularPlanProvisioningAddPlanResultUnknown

[sampertelus]

Can you find any solution for
Currently (iOS 14.2), there might be a bug in iOS SDK that returns unknown results before eSIM setup completion. More about it here

I'm having the same issue with IOS 15

I found the solution you need to move

API_AVAILABLE(ios(12.0))
CTCellularPlanProvisioning *plan;
API_AVAILABLE(ios(12.0))
CTCellularPlanProvisioningRequest *request;

before the function declaration

API_AVAILABLE(ios(12.0))
CTCellularPlanProvisioning *plan;
API_AVAILABLE(ios(12.0))
CTCellularPlanProvisioningRequest *request;

RCT_EXPORT_METHOD(setupEsim:(NSDictionary *)config

                  rejecter:(RCTPromiseRejectBlock)reject) {
    
    if (@available(iOS 12.0, *)) {
        plan = [[CTCellularPlanProvisioning alloc] init];
        
        if (plan.supportsCellularPlan == NO) {
            NSError *error = [NSError errorWithDomain:@"react.native.simcardsmanager.handler" code:2 userInfo:nil];
            reject(@"1", @"The device doesn't support a cellular plan", error);
